How to replace and axle shaft and/or a wheel hub bearing assembly

After a day of fun you Jeep may look like this:


On my Jeep I have aftermarket wheels so I am able to access the main hub nut with the wheel still on.

Start by removing the cotter pin:


Then the cap:


And behind the cap is a spring (shown on left):


Next, use your trusty 36mm socket to break that nut before you take off the wheel:


With the nut torqued to 175ft/lbs and rust/dirt seizing up the nut, it isn't a surprise that a cheater bar helps In this case it is my old tie rod.


Now jack up your axle:


And remove the wheel, place it under your sliders if you have them or under your hub in the event your Jeep falls off the jack, it won't crash onto the ground:


Next, remove the caliper bracket (2 x 18mm bolts) and hang it from the spring via wire or zip ties:

Next, on the back side of the knuckle there are three bolts. They require a 12pt 13mm socket to remove them and can be stuck on there pretty good as well. The first one is at the top, then the other two are on the lower left and lower right (imagine a triangle):

At this point you can remove the hub. In my case the outer axle shaft came out with it since I blew up the joint:

This leaves you with steering knuckle, minus the outer axle shaft:

Remove the inner axle shaft and replace:

When putting everything back together there isn't anything special to do.
  • Torque the 3 12 pt 13mm hub bolts to 75 ft/lbs.
  • Torque the main 36mm hub nut to 175 ft/lbs.
Tricks/suggestions:
  • If you don't have a wheel where you can get easy access to the big hub nut to break it, remove thw wheel, and then have someone apply the brake while you loosen the nut.
  • Some of the ABS cables get in the way, just remove them from the bracketry and push them to the side when getting to the hub bolts.
  • If available, be sure to use PB Blaster on the bolts/nuts if they haven't been removed in a while. Last thing you want to do is snap a bolt!
  • My only other hint to this procedure is that it is easier to get to some of the bolts if you turn the wheel to either side.

Ok, I installed a new axle shaft today. After Napa shipped in an axle with busted tone rings, I picked up a remanufactured unit for $116 after tax. New units are cheaper then remanufactured units (go figure) but they couldn't get a new one until Thursday and work doesn't like me working from home all the time

New axle shaft:


Review what we have here to put back on, Cotter pin, castle washer, spring washer, axle-->hub nut, washer, 3 hub nuts, and a socket that doesn't belong in the picture. What is missing? The two bolts holding on the caliper bracket to the knuckle.


When you slide in the new axle, make sure the splines are clean (as they go into the diff and we want to keep that fluid clean), and try not to let it touch the inside of the axle tube much since it is dirty in there.


Toss on the hub and bolt it back up, remember these three bolts require 75 ft/lbs of torque.


Install rotor and brake caliper:


Then reinstall the tire and torque hub-->axle nut to 175ft/lbs:

Is it really necessary to remove the 36mm nut just to replace the hub/bearing assembly. A little confused since you did more than that.

Yes, it is necessary to remove the 36mm nut if you are only changing the unit bearing. The axle is what the nut is bolting onto. The axle sticks through the hub/bearing; The axle is secured to the hub via the 36mm nut.

Sorry for bringing this back from the dead. But since i'm replacing the hub also do I need to remove the 36mm axle bolt? Or can I get away with leaving it on there?

If you are replacing the hub and shaft, you still need to take the 36 mm nut off to put on the new shaft unless you get one with the new shaft.

I'm replacing my wheel hub assembly and thanks to this post I can finally do it myself. Back then, i had to take my truck to the shop just to get it replaced.

Sorry to bring this back from the dead again lol. But I was just checking to make sure there are no surprises when I am taking this apart or putting it back together. Once again JeepForums has always came through when I needed help. On a side note I just picked up a axle today for 48$ plus 12$ core.
