CJ axles questions

Well, in the rebuild process of my CJ7, it's now time to rebuild the axles

I have the stock D30 front and AMC20 rear

First some questions regarding the front axle:
- How do I get the whole steering knuckle off? Anywhere on the web with some details of the rebuild maybe?
- How I change the bearing at the just behind the yoke? I mean, how do I get it out?

Rear axle:
- How to get the axles aout of the axletube? Do I have to un-bolt something in the housing or?

Thanks

If you send my your e-mail address I'll send some exploded drawings from the '78 FSM. They're too big to post.

To get it apart, you basically unbolt things, starting from the outboard end. There aren't any special tricks. After the spindle is off the axle shaft,the U-joint and stub axle will pull right out. There's a threaded hole in the end of the stub axle that you can screw a bolt into for a better grip.

To get the knuckle off, after removing the steering links, remove the lower ball joint nut and back off the upper nut flush with the top of the stud. That keeps the knuckle from falling when the tapered studs break loose. Then break the studs loose with a hammer. After they're loose, remove the upper nut and the split ring seat. You may need a special wrench for that, or you may be able to loosen it with a punch and hammer.

It'll make sense when you see the drawings.

EVERYTHING's easy for the guy who doesn't have to do it.

Many people say to remove the hub from the shaft on the rear 2 piece amc20 shaft. I wouldn't bother.

Remove brake line, remove E brake cable, remove 5 bolts from Axle housing flange and slide the shaft out.

next I'd suggest, you cut the bearing off the shaft to get t backing plate off and throw the shaft to the side. Order new One piece shafts and install those.

What now? I need to get those ball joints out, but I just can't do it
Are there any snap rings or something I need to remove first?

The ball joint studs are tapered, and they get stuck in pretty tightly. You need to beat against the eye to jar them loose. With a big hammer, beat the eye straight toward the differential. That will jar the taper loose and the stud will fall free.

Then the joint is pressed into the knuckle, and to get it out you need a press. The FSM pages I sent show how using the factory tools, but with a little ingenuity you can set up a press to do the job.

I usually smack the side of the knuckle (tapered hole) with the BFH...this usually breaks the hold on it and it all comes apart.

This usally works real well on the TRE's....one or two good smacks the the ball joints fall right out...don't even have to tap on the threaded rod of the boll joint.

Thanks to you all!

Jim and Dawg's advice worked perfectly!

Now I just need to smack some new ball joints in place to get on with my project

Dang, you guys are great!

You will need to seat the split ring to 50 FT for the correct preload using the tool below.

Ummmm....I can start screwing my split ring at the top and go on until it comes out in the bottom?
