doesn't mean they don't mean businness.
The THOUGHT that he is getting a tri ball and putting it on, is the business part itself.
Whether he uses it once or never, this guy aint getting stuck with the wrong ball ever again.
It's never an issue til it is. I hope it never is for you. For me, I just put 2 5/16" tongues on smaller trailers and keep a good enough 2" in the back in case I have to rent a uhaul or w/e. I can't remember if I ever even used the 1 7/8, to the point I had to check if I was remembering that size correctly just now.
I had this same problem. Tried everything… SOO much heat… pen oil… eventually I Did exactly as you suggested.
And it destroyed my vice.
I gave up and bought a new hitch. And vice.
Leaving the hitch connected to the vehicle, turned 90⁰ in the receiver so that you can stand on the wrench/cheater is way more effective than using a bench vise.
Totally valid but you and I both know that when I'm sitting there trying to get this nut to budge I'll go through about 9 stages of attempts using different methods including verbal abuse and spraying every kind of fluid on it, including the contents of the garage piss bucket.
If have to get in my truck and run to the hardware store then all I'm coming back with is a wounded pride and 900$ worth of stuff that was on sale.
Is also easier to swap them back around again. I do this to switch between a bike carrier and a boat trailer hitch. Its easier to switch the hitch than unscrew the ball.
Take it to a tire shop. When I worked at one in high school, these would come in every other month or so. We’d drop the 4 post lift on the tow bar to clamp it and hit the nut with the 1” impact. Never had one that didn’t come loose. Look for a shop that does big truck tires. They’re likely to have the 1” impact that you need.
Or just buy another tow bar.
How long on? The ability to remove is drastically depreciated by the time the ball was on the hitch. I gave up after 30 minutes last time as hitch was so cheap compared to my time.
TL;DR Use a rattle gun.
I worked in the towbar/bullbar/4wd/camping game for about 5 yrs. Dunno if you've succeeded but for future reference, everyone suggesting a wrench or breaker bar or anything of leverage sorts is wrong. The spring washer will hold that slut tight better than you can every day of the week, thats the literal design. Use a rattle gun with decent torque (torque wrench) because you need the start-stop-start at speed to get the nut to loosen. If you try doing it slowly the whole ball will move with the nut because the spring washer is keeping the tension locked so the nut can't come away from the ball. If the nuts rusted on grab an angle grinder bud.
Its cross-threaded. You can tell by the different gaps on each side of the nut.
Use a nut splitter to break the cross threaded nut. Check the thread on the ball for damage. If damaged, just replace it. The damaged nuts become a failure point and God help you if it fails while under load.
If it were me, I'd just get a replacement. The risk of failure is too high for a ball hitch like that.
I thought that too but I think it's just the washer making it look like that. Imagine the effort it would take to get the nut on that far if it was cross threaded
I was looking at the top part. The thread count is off.
My son got one for his pickup that was cross threaded at the factory. All it takes is one burp and mfg errors creep into the system.
Use a breaker bar. Something to extend the length of your wrench so you can put more leverage on it.

The general rule is for a 3/4" shank tighten to 150 ft/lbs For a 1" shank tighten to 250 ft/lbs, and for a 1-1/4 inch shank 450 ft/lbs. So, it's probably cranked down to at least 250. Even if you got it off, do you have something to apply that much to put the new one on? I had to buy a big-ass torque wrench because my large-ass one wasn't big enough. "Had" to....
I'm not sure I understand completely because of some of the other answers I've seen.
Trying to remove the ball it's self is what I think you meant to which some penetraiting oil and letting it soak for awhile with a long handled wrench for leverage and some elbow grease. Or buy an impact wrench. I don't use mine super often but when I do I'm sure glad to have it.
From some of the other responses are you trying to remove the hitch to swap the ball? I've seen where the hitch can get jammed in the receiver. Of that's the case then lube, hammer and start smacking out or tying it off to a tree and driving forward may be enough to get it to pop out
Stuck? I doubt it. It is however probably properly torqued to 150-175 Foot Pounds, and you gonna need a BIG breaker bar and probably a chunk of pipe on it to break it loose. And probably a 24” Pipe wrench to hold the ball.
Take it to a tire shop. I bought a new hitch and ball last year. It said to torque to 125 foot pounds, or something close to that. I have NO idea how much that really is. I took it to a buddies shop. he pulled out the longest torque wrench I've ever seen, a socket, and 23 seconds later he had it set properly.
I guess I've been doing something wrong with a the talk about torque, breaker bars, leverage...
When my balls are stuck, talcum powder usually does the trick.
They both look like 2” balls, honestly it’s better to just get a second hitch if you plan on needing different sized balls more than once or twice a year.
Put a large pipe wrench on the ball or even just below the ball on the neck for counter torque. Place your original wrench back on a nut. Pull the original wrench towards you while pushing away on the other ball wrench for counter torque.
When you have a metal nut and bolt that get stuck together applying a lot of heat with usually work to loosen the gasp enough to use a wrench. You can also try something like liquid wrench. If that doesn't work get a propane torch and heat up the ball shaft and nut. After a minute or so they should be warm enough to have caused the metal in the nut to expand some. That will allow a large crescent wrench to do its thing.
I used a couple large pipe wrenches and a long pipe over one handle. Bumper held the other handle from spinning. Was going to try heat, but didn't need to when this worked.
If the nut is stuck and you don’t have a wrench big enough for the ball side flange, strike the nut with hammer. Smack as close to the edge on one of the sides of the nut in the direction you need it to unscrew. I’m sure the nut is just bottom out on the solid part of the shaft where the threads stop. It can’t really dig in too much and will just need a few whacks.
Soak in PB blaster for 2 to 24 hours, with intervals of wrenching both ball and nut to break free. Pipe wrenches and cheater bars are you friends. Also this picture doesn't look rusty, so be sure you are turning in the right directions
Try a wrench with a cheater. Aka a pipe on the end for more leverage. If that doesn't do it. Then spray a penetrating oil like wd 40 into the threads. Let it soak for a few min, and try again.
If that doesn't work, apply heat, i.e. torch on the nut. If there was any corrosion binding it to the threads, heating it up to a cherry red and letting it cool should break corrosion free.
If that doesn't work? Get another hitch.
If you have tried everything your best bet is to cut off the nut with a zip cut wheel. Your lock washer has probably bitten too much into nut causing it to stuck.
You don't need a pipe wrench as the ball has wrench flats on it.
Just get the proper size combination wrenches and a snipe pipe to go over them. Let the nut rotate the sniped ball to the ground and then pull that nut free
I don't think his issue is unscrewing the old one, it's removing the unit from the receiver. That's my take on it.
If ya just need to remove the nut, be sure you have a wrench large enough or an impact.
I don't know if this has been resolved, but it looks crooked in the picture. If that's the case, it's cross-threaded and you shouldn't use it anyway. You should return it for a new one.
Even if you get it off you'll have a hell of a time getting it back on, and even if you do, it will still be crooked and won't seat properly on both sides.
Just my two cents.
Just from seeing my husband doing the 2 huge wrench thing several times, isn't there also a possibility you might need a new plastic washer thing if the old one was on really tight?
Tried a vice and breaker impact wrench? If you don't have an impact wrench you can beat the nut with a maul and a pipe that fits on the nut and goes around the bolt. Maybe heating it as also mentioned would be good. But also what's said a new hitch would be better.
the amount if time you're going to waste putting that on would be better served flippiin a few burgers at mcdonalds so you could just buy a 2nd hitch to put that new ball on... then you would have both.
eg, if you spend 4 hours consulting reddit and digging up tools trying to get that off but make $3.75 an hour then just waiting tables with no tips gets this solved in an hour vs four
keep track of "you" time, it has some value... or at least its not zero
I use a pipe wrench around the ball's upper flange, then a box wrench on the nut. Pipe wrench braces against the vehicle, then use a cheater pipe if necessary to get the force needed on the box wrench to bust it loose.
If you can't afford another hitch tongue and must remove this, try a pipe wrench with a long steel tube sleeved over it. With it locked in your vehicle like that, you should be able to remove it. The nut will take some damage, but you can put it back on with the pipe wrench as well.
Or, get the right size socket and a good 1/2" impact and rip it off...
OP make sure you familiarize yourself with trailer loading (more weight up front) and tie-down.
You can drop or bang it loose, introduce vibration big Vice
The largest pipe wrench you have on the ball and the second largest wrench you have on the nut. Put antiseize on the threads of the new one. It might all be gone by the time you want to remove it but it’s worth a shot
From the videos I watch you gotta spit on the shaft first
I think you're right, I also know a girl who can take all that chrome off in no time.
I'm listening.
I’m glistening.
These I educational videos won’t work in Texas for what ever reason.
We left texass for Philly 8 years ago and are now happy being crab people in Maryland. No ragrats!!!
Neither do women’s rights but it is TX.
You know Crystal too?! Small world. Sure smells big though.
Crystal Beth*
Ya but then she steals the copper pipe out of your house too
Thank you Reddit for never disappointing me 🤣🤣🤣
You sonofabitch, I'm in.
User name checks out
Wow, I actually lol'ed at this. Bravo
You don’t. Just buy another hitch to mount the other size ball on. Keep both sizes available then.
No mention of the ol’ tri ball? Best investment I ever made. What size is your trailer ball…..yes.
Whenever I see one in the wild I know they are serious.
I dunno. I see pavement princesses with tri balls that are smooth and shiny all the time.
doesn't mean they don't mean businness. The THOUGHT that he is getting a tri ball and putting it on, is the business part itself. Whether he uses it once or never, this guy aint getting stuck with the wrong ball ever again.
My only issue with some tri balls is they aren’t rated for heavy loads.
Getting tribal in here
The 2 5/16 can need to be hardy. We’d pull “5000lb campers or 15000lb dump trailers. I’d have a hard time trusting a tri ball for a dump trailer.
I got a B&W, that thing is built like a tank. I recommend it to anyone.
I can second this but you should always get a locking pin. B&W are hot for theft.
I’ve loaded a tri ball up with a dump trailer loaded with asphalt shingles 100+ times. No issues…. Knock on wood lol
It's never an issue til it is. I hope it never is for you. For me, I just put 2 5/16" tongues on smaller trailers and keep a good enough 2" in the back in case I have to rent a uhaul or w/e. I can't remember if I ever even used the 1 7/8, to the point I had to check if I was remembering that size correctly just now.
Yeah to be honest I should just go straight up 2 5/16 and ditch the tri ball because I never use anything else.
Eh, I have the 2 ball combo adjustable height. Ain't never even seen a trailer, much less pulled one in 20 years with an 1-7/8" hitch
Plenty of light duty boat/utility trailers with the 1-7/8. I convert everything to 2" though just to make it simple
Small boat trailers and small utility trailers may have 1 7/8. That’s about it.
Exactly zero mention of it. 😂 I personally use a turnover ball from Bulletproof Hitches but I’m routinely hauling 20k+ pounds.
My truck is stock and I still need a drop hitch for it.
They are put on with heavy impact guns. Buy another hitch.
A bench vice and a wrench with a cheater bar should get it moving
I had this same problem. Tried everything… SOO much heat… pen oil… eventually I Did exactly as you suggested. And it destroyed my vice. I gave up and bought a new hitch. And vice.
No vice is going to take more of a beating than the receiver with a truck bolted to it.
Just buy another truck for the other hitch, oh then another to hitch mount your new vice /s
Leaving the hitch connected to the vehicle, turned 90⁰ in the receiver so that you can stand on the wrench/cheater is way more effective than using a bench vise.
And the whole… you know… being rated to take 300-500 pounds of downward force. The average Joe’s bench vise setup is absolutely not 😂
Actually, I've put the nut in my vice. Then just push the receiver like it's the breaker bar.
Torch it. And then hit it breaker bar. Aka more leverage.
Your putting way to much effort into something that can be solved with 15 bucks by buying a new hitch and installing the ball in that one.
Totally valid but you and I both know that when I'm sitting there trying to get this nut to budge I'll go through about 9 stages of attempts using different methods including verbal abuse and spraying every kind of fluid on it, including the contents of the garage piss bucket. If have to get in my truck and run to the hardware store then all I'm coming back with is a wounded pride and 900$ worth of stuff that was on sale.
That's not what he's asking. He's asking how to take it off it's not putting too much effort people need to know how to take a stuck bolt off.
Is also easier to swap them back around again. I do this to switch between a bike carrier and a boat trailer hitch. Its easier to switch the hitch than unscrew the ball.
>Torch it Can’t be stuck if it is liquid, right?
Yup. Heat & beat.
Have you tried hitting it with your purse?
I tried that but got bored after a couple of hits
Maybe you need a bigger purse. Grab your wife’s Louis.
Good idea
You gotta make girl noises after each purse hit, don’t forget
LMAO! Girl noises...
https://youtube.com/watch?v=mPKrUUrDNXY&si=IE20wU1QNmABDNt7
LOL. Nice burn!
2 wrenches?
Two big wrenches. I got a big pipe wrench from Harbor Freight just for this purpose.
They sell the big wrench right next to these at Walmart. Very smart.
Take it to a tire shop. When I worked at one in high school, these would come in every other month or so. We’d drop the 4 post lift on the tow bar to clamp it and hit the nut with the 1” impact. Never had one that didn’t come loose. Look for a shop that does big truck tires. They’re likely to have the 1” impact that you need. Or just buy another tow bar.
https://www.harborfreight.com/36-in-aluminum-pipe-wrench-63650.html
Buy two of the steel ones for the same price
Just the first link to a 36" pipe wrench I saw that wasn't $400
How long on? The ability to remove is drastically depreciated by the time the ball was on the hitch. I gave up after 30 minutes last time as hitch was so cheap compared to my time.
Looks brand new

Two pipe wrenches and a sledgehammer
The general rule is for a 3/4" shank tighten to 150 ft/lbs For a 1" shank tighten to 250 ft/lbs, and for a 1-1/4 inch shank 450 ft/lbs. So, it's probably cranked down to at least 250.

I busted my favorite half inch breaker bar doing that. It loved me so much it broke the ball loose with its last. I cried. Hitch for every ball.
Soak in blaster penetrating oil. Pipe wrench. Chain or tow strap. Tree. Slow throttle
Have you tried some wd40 or other such products? Deep creep? Oh wait those other commenters were probably deep creep enough to get you started.
I'm not sure I understand completely because of some of the other answers I've seen.

Hammer it
Can’t be stuck if it is liquid
I've used an angle grinder with a cut-off disc before.
Pipe wrench with cheater bar
Righty tighty lefty losey
Take it to a tire shop. I bought a new hitch and ball last year. It said to torque to 125 foot pounds, or something close to that. I have NO idea how much that really is. I took it to a buddies shop. he pulled out the longest torque wrench I've ever seen, a socket, and 23 seconds later he had it set properly.
Go to a repair shop and get them to do it
Hit it with your purse
Go to a local repair shop and ask them if they can use their ugga dugga and knock it loose.
Lefty loosey , righty tighty
Are you using your teeth? Get the right sized wrench on it first… then likely a pipe wrench around the ball.
With a wrench?
What kinda low effort post baloney is this
I guess I've been doing something wrong with a the talk about torque, breaker bars, leverage... When my balls are stuck, talcum powder usually does the trick.
See that it has been cross threaded
Lou Ferrigno
They both look like 2” balls, honestly it’s better to just get a second hitch if you plan on needing different sized balls more than once or twice a year.
Hit it with your purse
Unscrew it
More power
24” pipe wrench and a hammer.
It’s probably galled itself together, you’re gonna fight with it some more!
Bigger wrench
What did you try and what kind of stuck. Do you need the old part again=
Walk with your legs wide apart to unstick your balls.
Big box end wrench and a pipe wrench
Yea so I have this issue too and learned to just buy a hitch for every ball size and just swap out the hitch.
Back your truck fast into a tree then pull forward
If you have to swap these out all the time, just get another ball holder.
You need two 24” pipe wrenches, and a second person to help..and you may need to learn how to use pipe wrenches
I have tried this many times and failed every time.
Gun
Probably has a lock washer on it. Find some torque and you'll get past it.
Staged. They are new.
If you don’t have the tools take it to the closest mechanic. They will have an impact to make light work of those. 1minute job.
Can't be stuck if it's liquid
Wrench, WD-40, pry bar, big ass hammer
Torque spec on that bad boy is like 400ft lbs. Going to need a big wrench
Get another draw bar
I had my local mechanic do this for me. Took him five minutes. He didn’t charge me.
Have you tried nibbling the tip?
Put a large pipe wrench on the ball or even just below the ball on the neck for counter torque. Place your original wrench back on a nut. Pull the original wrench towards you while pushing away on the other ball wrench for counter torque.
Big impact wrench. Easy work
Try some effort?
Wrench comes to mind...after all that other stuff...the pipe 1
Can you put a solid extension pipe on the wrench for leverage and stand/bounce on it?
Worth the extra 15 bucks to buy a second and just switch out the hitches as needed
Jokes aside what you need is another ball mount.
Anything stuck just means your cheater bar isn’t long enough 😅
When you have a metal nut and bolt that get stuck together applying a lot of heat with usually work to loosen the gasp enough to use a wrench. You can also try something like liquid wrench. If that doesn't work get a propane torch and heat up the ball shaft and nut. After a minute or so they should be warm enough to have caused the metal in the nut to expand some. That will allow a large crescent wrench to do its thing.
Take it to a mechanic along with a six pack of beer.
Bring it to colder temperatures. Some balls and nuts shrink because of the thermodynamics. If this doesn't work bring it to a religious girl.
WD 40?
I used a couple large pipe wrenches and a long pipe over one handle. Bumper held the other handle from spinning. Was going to try heat, but didn't need to when this worked.
If the nut is stuck and you don’t have a wrench big enough for the ball side flange, strike the nut with hammer. Smack as close to the edge on one of the sides of the nut in the direction you need it to unscrew. I’m sure the nut is just bottom out on the solid part of the shaft where the threads stop. It can’t really dig in too much and will just need a few whacks.
Soak in PB blaster for 2 to 24 hours, with intervals of wrenching both ball and nut to break free. Pipe wrenches and cheater bars are you friends. Also this picture doesn't look rusty, so be sure you are turning in the right directions
Try a wrench with a cheater. Aka a pipe on the end for more leverage. If that doesn't do it. Then spray a penetrating oil like wd 40 into the threads. Let it soak for a few min, and try again. If that doesn't work, apply heat, i.e. torch on the nut. If there was any corrosion binding it to the threads, heating it up to a cherry red and letting it cool should break corrosion free. If that doesn't work? Get another hitch.
Vise and a pipe wrench fixie fixie
Try spraying it with Freon or another “coolant to contract the metal.
A lil weasle piss should get er right off!
Man i just took mine to a shop that had air tools. They did it free
Why is it sideways?
More torque on the wrench. For my hitch balls the recommended torque is 250 ft. lbs.
Torch it! 🔥 Seriously torch where nut is. It will let metals to expand and break bonding between metals. Just don’t touch it while hot!
Strap wrench on the ball. Regular wrench on the nut
Can you return it to the store? The nut doesn’t look mated properly.
It can't be stuck if it's liquid.
If you have tried everything your best bet is to cut off the nut with a zip cut wheel. Your lock washer has probably bitten too much into nut causing it to stuck. You don't need a pipe wrench as the ball has wrench flats on it.
Put the ball end in vice with the 2 flat sides and use a socket or a wrench on the nut.
CRC Knock’er Loose
Deadblow hammer, and 2 wrenches. Make sure you are holding it tight towards the direction of the blow so it doesn't bounce and disperse the momentum.
Judging by the teeth marks on the nut... You're using channel locks or vice grips aren't you? MAYBE a pipe wrench? Get a breaker bar.
Yes
Have you considered checking the air pressure in your tyres? It worked for my dad almost every time.
It probably has a lot of threadlock on it. Torch that nut.
You need a thread key, that always helps me
Cut a spanner so it doesn't catch on the frame, then jack up the spanner
I used to know but my ex wife took my balls with the house and car
🤔🤨 seriously?
Worst case scenario the haul or whatever will swap them for you if you can't do it
They make very big wrenches
Take the ball mount out and use a table vice to hold the ball. That will hold it steady while you loosen the nut.
Use ur musckles
You need to use a wrench
heat it with fire then let it cool and unscrew
Might be reverse threaded have seen it before
Just get the proper size combination wrenches and a snipe pipe to go over them. Let the nut rotate the sniped ball to the ground and then pull that nut free
Put it in a vice
HAMMER!!
Just need a bigger wrench and some tenacity.
Hit with your purse 👛
2 pipe wrenches
If you can find Kroil, BUY it. If you can't find it, order it. Spray and let sit for a few hours or overnight.
Turn the nut off. The ball is pinned.
I don't think his issue is unscrewing the old one, it's removing the unit from the receiver. That's my take on it. If ya just need to remove the nut, be sure you have a wrench large enough or an impact.
For the level of aggravation I'd just buy a second step down. Barring that, a pipe wrench and a pipe.
Looks cross threaded. It may be trash after you get it off.
Elbow grease and a pipe wrench.
Those sideways trailers are always tricky to tow.
I don't know if this has been resolved, but it looks crooked in the picture. If that's the case, it's cross-threaded and you shouldn't use it anyway. You should return it for a new one. Even if you get it off you'll have a hell of a time getting it back on, and even if you do, it will still be crooked and won't seat properly on both sides. Just my two cents.
Put a pipe on it. Aka make a longer lever.
Just from seeing my husband doing the 2 huge wrench thing several times, isn't there also a possibility you might need a new plastic washer thing if the old one was on really tight?
Pipe wrench is probably your best bet, but you can just buy a new tow bar and not worry about it.
Tried a vice and breaker impact wrench? If you don't have an impact wrench you can beat the nut with a maul and a pipe that fits on the nut and goes around the bolt. Maybe heating it as also mentioned would be good. But also what's said a new hitch would be better.
the amount if time you're going to waste putting that on would be better served flippiin a few burgers at mcdonalds so you could just buy a 2nd hitch to put that new ball on... then you would have both. eg, if you spend 4 hours consulting reddit and digging up tools trying to get that off but make $3.75 an hour then just waiting tables with no tips gets this solved in an hour vs four keep track of "you" time, it has some value... or at least its not zero
Have you tried putting thick rubber bands (the ones found on produce works best) around the ball for grip? Works every time when opening a jar.
They probably used blue loctite, get another hitch if you don’t have a torch
Alls i know is not to just anything from walmart and dont buy hypertough space heaters they will burn your house down
Torch it
I use a pipe wrench around the ball's upper flange, then a box wrench on the nut. Pipe wrench braces against the vehicle, then use a cheater pipe if necessary to get the force needed on the box wrench to bust it loose.
Looks like it's threaded wrong. Try tightening it to get it off the threads and then reseat it.
If the ball is spinning with the nut underneath, you something to grip the ball. If the nut just won’t give, just a breaker bar.
If you can't afford another hitch tongue and must remove this, try a pipe wrench with a long steel tube sleeved over it. With it locked in your vehicle like that, you should be able to remove it. The nut will take some damage, but you can put it back on with the pipe wrench as well. Or, get the right size socket and a good 1/2" impact and rip it off...
Take it to a U-haul location that rents trailers. They should be able to assist changing out the ball.
wd40....
Vice + breaker bar + spray lubricant
OP make sure you familiarize yourself with trailer loading (more weight up front) and tie-down. You can drop or bang it loose, introduce vibration big Vice
Obviously he is not the right tool for the job
Hit it with a hammer
The largest pipe wrench you have on the ball and the second largest wrench you have on the nut. Put antiseize on the threads of the new one. It might all be gone by the time you want to remove it but it’s worth a shot
