I think I know the answer to this one but thought I'd ask anyway. I'm getting ready to replace the upper & lower ball joints on my 90 xj 4x4 both sides have about 1/16th or more of play, so does it make sense to replace the axle u joints also? I've never done this before is it a tough job?

It's not tough if you have the right tools. If you don't, then it is a nightmare. You need a ball joint press, with the 4wd adapter kit. Sometimes getting the knuckle to drop off is a pain, but if you use the BFH and hit it on the flat spot on top, it should eventually pop off.

I would go ahead and replace my axle ujoints, if I didn't know the last time they had been done.

thanks for the info. I borrowed the tools (separator & press) from O'reillys but I don't know if the press has the 4wd kit or not. The press kit came in a carry box with several adapters and such. Just don't know if any of the adapters are the 4wd kit or not.

Hey thanks watched the youtube and that was just what I needed to see. I will be doing mine tomorrow.

It should have everything you need, other than a bunch of muscle

I broke my Craftsman 2' breaker bar when I did mine. Key when pressing them out is to use forceful quick turns. Don't go slow and steady when it starts getting hard.
