Changing unit bearings. Need to get new axle nut?

Can the 175 foot pound axle nut be reused after replacing the unit bearing? I'm seeing some conflicting info online. Dorman products places a "It Is Recommended To Replace Every Time They Are Removed" statement on their website. Of course they're in the business of selling product, but also in the business of not getting sued. I'm definitely leaning toward taking their advice.

What is the experience others have had?

I have used the same nuts probably 50 times with no issue.

Never even thought of changing them. But, I always use brand new cotter pins, those will break at the bend quite often.

Same here. I've never replaced the nut when replacing a busted shaft or unit bearing. I do have a few spares from the junk yard in my tool box. But yeah, always just re use what's on there. As far as I know they may well be 22 years old and from the factory

Yes those nuts are not torque to yield like head bolts are.

Wicked tight those things are. Start PB blasting every bolt/nut you're going to have to remove ahead of time and annoint them ceremonially a few times a day with liberal doses of PB. I've had no problems with re-using these either, and I like to antiseize them so it's easier the next time you pull them off again.

Thanks for the feedback guys. Just to update, the nut was relatively simple, breaker bar with PB Blaster (applied over several days in small amounts) and it came off. Ok, so we had to stand on it, but it came off. The real trouble was un-fusing the hub from the spindle. Had to apply pressure with a puller, then tap on the center driver of the puller, then add more pressure, then tap. Over & over. It was a real bugger, but eventually came off.

I know its too late for you, but this may help someone else. The trick is to back out the bolts on the backside, leaving some threads in the hub an put a socket in there, wedged up against the knuckle, then turn the steering wheel into it to break it loose. My description may be a little fuzzy, it's been a couple of days since I did this, but I think you get the idea...

"Put a socket in there..."

Where exactly?

In between the yokes of the axleshaft so it can't bend/turn where the ujoint is.

The trick is to use a gear puller on a work bench



And the real trick is to wheel with shafts ready to install

Somewhere on the forum, or on Stu Olson's site, there is a writeup on this process, including the "socket technique" of getting the unit bearing separated from the hub. At work, I am somewhat limited by firewalls, but I will try to find the link and post it in.

Try this: http://www.jeepforum.com/forum/f12/a...a-30-a-360209/

It may not cover the unit bearing, and I cannot see the photos at work, but from the narrative it seems this socket technique is described, and likely there are illustrative photos.

You'd never believe some of the techniques I've resorted to in undoing those axle nuts, not just on Jeeps. I now have a mongo powerful impact wrench, and an "I'm overcompensating" air compressor so it's a simple process of brute force.

I had mine out in ten min in the driveway and didn't have to pull the axle or replace seals. Either way...
