Rear driveshaft removal

Replacing my u-joints at both t-case and axle and was wonder if there is anything I should be aware of if I remove my rear drive shaft from the t-case.

Nothing special except you should paint marks on your shaft so it can be reinstalled in the same position.

Also, pick up a 1" copper fitting brush and cut the handle off and run it thru the bore of each yoke with a drill after you pull out each joint. Gets rid of all the crap and rust before you reassemble

And if you can't get the snap rings out, give the U-joint cap a wack with a hammer.
It will drive the cap down slightly and ease the pressure against the snap ring.

The normal force on the U-joint as it spins causes the caps to push outward against the snap rings pretty much pinning them in place and sometimes a bugger to remove.

Well, last night I tried to tackle removing the u-joint at the axle. I got the snap rings out but not without a little fight. That became the easy part. I tried to a socket extension with a hammer to remove the u-joint but it didn't budge. I than got a c-clamp out to see if I could get the u-joint to move so I could use the hammer and socket extension again to finish the removal. The c-clamp didn't even move the u-joint. So i made no ground on my project. Anyone have any suggestions for removing the u-joints? I believe they are original from 1998. Since they have been in there for so long it almost looks like the u-joint is apart of the drive shaft.

The HF u-joint press, a hammer and some PB blast/liquid wrench

On my 99 I had the same issue. I soaked the yokes in PB Blaster for an hour then removed the clips. After that the u-joint caps would not budge. I wound up using a propane torch to warm up the yoke. I didn't want to use too much heat as not to warp anything. A few licks with a hammer and a socket and they came right out.

I second Jimsjeep recommendation on using something to clean out the yoke, it will make installing the new u-joints a lot easier. I used a fine grit sandpaper 400 grit or higher.

When installing the new u-joints be sure to keep the bearing caps on so you don't have a needle bearing fall out of place in the cap. I had to redo one end twice because I couldn't get the caps to seat correctly.

First of all make sure to block your tires. No rear DS means nothing keeping it from rolling. Okay.

Gona pretend I didn't hear some of the stuff in here. Sounds like your first issue is getting hte c clips out. you can use a chisel to hit the clip from the outside in where you would grab with the pliers. This might pop it loose. Repeat on other side then pinch and remove. Use a BIG hammer and support it. Whack the U joint hard using a socket as the middle man. Don't bend the yoke ears.
