I crawled under my 96ZJ and noticed I have the U-joint axles, and they are BAD!!! I did not get a very close look at it yet, but I can just replace the u-joints right? Should be the same as changing the front u-joint on a rear drive shaft? Or do you replace the whole works axles and all??? I've changed them on the front of a 89 f-150 many of times... (I have 38s in the front welded spyders..) This procedure does not look bad, if it is the same for my 96... I can turn my front drive shaft about a quarter turn before the tires move... Lots of slop!!!! Thanks for any info!!!
