How do you remove the rear axle nut? [Confused]
I bent back the dimple on the nuts.
I have used 1-1/8" socket with a breaker and extension making for a 3ft handle with the 1/2" breaker bar bending but not turning the Nut. I then tried a 1-1/8" Combination wrench using the box end and hitting it with a 3 pound sledge, still nothing. Next I went out and bought a Harbor Freight 1/2" drive Earthquake impact gun with 600 ft lbs max. Again after 20 min of using the impact gun I ended up cracking my socket in two places.

WHAT AM I DOING WRONG???? [banghead]

I am going to get an impact 1-1/8" 6point socket tomorrow, but don't know what I am going to do to get the nuts off. I am thinking of torching the nuts and after that get out the abrasive blade and cut them off unless you guys have other ideas.

PLEASE HELP!!! [help]

When I did my first one I used a 1/2 inch breaker bar and a six foot section of pipe......it worked but I decided that was the wrong approach, especially as I watched the breaker bar bend.

3/4 inch breaker bar worked no problem on the other one. See if you can borrow one from a friend.

Get an Ingersol Rand Titanium 1/2 drive impact wrench it will remove the nut. I have yet to come across a nut that it cannot remove A bit expensive...but saves time, effort, and aggrivation.

Impact wrench generally wont break off the end of the axle, so I vote for that, but I have also done it with a breaker bar and a length of pipe....

At this point probably wouldn't hurt to start soaking the things in PB Blaster. Once you get your nuts off, [Big Grin] will you be able to get the upright off?

What Chris said - start soaking the long bolt that holds the upright to the lower control arm with PB Blaster or similar.

I have had the same problem once before. Either a torch will work, or what I did was take a small drill bit to the inside edge of the nut where the threads are. You may damage a few threads on the axle but this will get the nut off. (it worked for me at least.)

Soak your nuts.

I had the same issue. Right side came off fairly easy with a breaker bar and extension, after some soaking.

Left side I tried impact, breaker with 3 ft extension, soaking, swearing, heat, pleading, more soaking, sacrificing some virgin car parts, more swearing, more impact gun, and finally breaker bar with full length jack-handle as an extension. No dice.

In hind sight, I should have started soaking that nut a week in advance. I ended up replacing the entire upright and axle... and my breaker bar that ended up with a permanent set bend in it.

I'm guessing that axle nut had never been taken off from factory - on a '92 from the North East. It went past the 'rust' stage, and right into the 'fussed' stage...


Good luck, exercise extreme patience. Or just buy new stuff...

Remove the upright and axle as an assembly and take it to a local garage. They will have enough air pressure, air volume and a big impact to get the nut off. They should not charge you anything, give the guy who did it a tip and you will on your way.

The next issue is will the shaft come out of the hub?????????

My guess is if the nut is that frozen, then the axle/hub will be the same. At this point I would be looking at total replacement. Make sure the parts come seperately if used and apply anti sieze.

Is that related to shrinkage? (Steinfeld beach house episode)

Well, for some of us it's because we have oversized shafts for the parts used on them. [Big Grin]

LOL! Freeze Off does seem to work pretty well for most nuts [Wink]

I just got some grapefruit in my eye.

#1...That axle can be an unholy nightmare to get out it's corroded. Took us an acetaline torch, plus a big press and the heat from the torch wasn't kind to the wheel bearing.

3/4 impact works great. Like Dave says the next problem will be to get the shaft and the bearing out. Like Lewis said. Just replace with new.

Before giving up on a 1/2 impact gun, try having someone step on the brakes while you are removing the nut.

Also, you might try removing the quick coupler from your air line, and plumbing the air hose directly into your impact gun.

Watched Chris Windsor deftly remove one with a hand chisel this weekend before I could find him some MAAP gas. Once it deforms a bit it will break free.

Impact gun is one way but if you are doing this from home your compresor might not have enough PSI to work it free. Have a person step on the brakes and another with a 1/2 breaker bar and a long pipe. The pipe should be all the way down to the head of the breaker bar (then it wont bend). Always Always use a 6 point socket. NEVER use 12 point, 12 point will round off your nuts(he he). Use some of the local teens to help you they are always happy to show you how strong they are.

I GOT IT OFF BUT......

I ended up using my oxy/acetal torch and got the nut off, but now for the axle. HEHE
I have the complete upright out of the car and have removed everything down to the CV-joint and upright, but I can not get the axle out. Hmmm what to do? Ruin the the bearing to get the axle out then replace the bearing?

When it's reached the point where your BFH isn't big enough and you're moving on to torches and hydraulics, might be a good time to replace the bearing while you're in there anyway, no?

I was also wondering about the integrity of the axle nut and axle after I have torched them. So my list is new axle nuts and new wheel/axle bearings. The one piece used axles I got were not torched so I am not worried about those, but I do not want to sell the current ones to someone if they are heat stressed now making them softer.

$100 at 10-1 that heat and hydraulics will "mushroom" the threads or crack the upright. Bight the bullet and replace it all.

We had to destroy the axle to get the upright into the press in a way it wouldn't be damaged. Then 12 tons of pressure or so @ 800*F and that axle came out like it was shot from a canon...add to the shopping list one pair of clean underwear.

Next step, does the upright fit the upper and lower CAs?
