Replacing Front Axle U-Joints

The front axle u-joints on my 98 XJ have been squeaking like crazy when I turn. I sprayed them with WD-40 and the sound goes away.

Anyway, I'm trying to pull the front axle shafts to replace the u-joints. I have it all apart but I can't pull the passenger axle shaft. My book says I have to open a vacuum motor housing on the axle and pull some stuff out. I don't see anything like that on the axle. Do I have to open the differential cover and do something in there first to get the shaft out? I was under the impression they just kind of slide out but it isn't budging.

your book is referring to a vacuum disconnect that is on the older cherokees. just double checking but did you take the unit bearing off? if it is off than you might have to use some elbow grease to convince it to come out.

ya that vacuum disco is oldschool. There is no c-clips in the front. sometimes they are just stuck i mean they been in there a long time. Try tapping it in a bit first, then out with a prybar, itl come.

You do not have a vacuum motor on your axle as it is not a disconnect type axle.

Perhaps there is a C-clip that needs to be removed before the axle shaft can be withdrawn.

its probably just tight from being in for so long as stated, just go slow and check for any clips, i do not believe there are any clips there, but make sure the hub bearing and everything is off and out of the way.

Funniest thing I've read all day. Thanks for the laugh.

Yeah, the book is in the garage and the computer is in the house. I couldn't remember what is said to pull out of the housing.

Anyway, I've been bangin' the crap-ola out of both sides. They just won't budge. Right now I'm just trying to get the hubs off. I pulled the 36mm nut and the 3 smaller ones on the back. I may run to Autozone and borrow a puller. The rubber hammer is worthless and my 5 lb hand maul isn't doing much either.

I was just wondering if there was something in the differential, like c-clips. I'd like to avoid the mess of cracking it open, but I will if I have to.

I have a stupid question. Did you take the caliper and rotor off? I didn't see that mentioned. but ya, take the big nut (36mm) and the three bolts out of the back that go into the unit bearing, turn the wheel so you can get some room and use a 2x4 or something and beat the crap outa the edge of the unit bearing, it will be tight. I used a 2lb brass hammer on one of mine, the axle came with it and I had to use a puller to get the hub off the spline, the other came no problem. No C clips in a Dana thirty.

Those who say it cannot be done should be quiet and not interrupt those whom are doing it.

"Yeah, the book is in.."

No need to explain. "Pull some stuff out..." is all that needs be said around here. Belive me.

I think I just schmucked up my hub assembly. I went and got a slide hammer and gave it a few whacks. Pulled the hub assembly in half. I'm lookin' at bearings right now. I'll try to get a picture. I still can't get that back half to separate. I just tried a 4 ft. iron pry bar and my hand sledge. She's welded on there. Any ideas?

No. I just collect/own a lot of "gear." I'm an avid outdoorsman. I like gadgets , tools, and "stuff."

Here's where I'm at. I'm assuming I'm now in for a new hub assembly. I just want to know how to get that friggin' thing off. I've been beating it like a red-headed step child and it won't budge.

Take a big flat head straight slot screw driver with a stubby end (not sharp) and place it between the hub and brake back plate and hit it with small ledge hammer it will slowly break the rust bead around whats left. You could also use a large chisel. The force of the wedge will break the unit free. Good luck, and wear safety glasses unlike these clowns on TV with all the cool tools and no brains!
