I needed a car for my daughter to drive so she'd quit driving my JK. I found and bought a 1994 Grand Cherokee Limited with full-time 4WD that needed work. The seller told me that the driver's side CV axle shaft needed to be replaced. After looking underneath I noticed the boot on both sides were torn so I talked them down and took it home.
Before I worked on the Jeep you could hear loud popping noises and the front end felt like it was catching on something. After replacing the axle shafts the noise is still there. I'm now thinking that I need a new diff.
Yesterday I was at the local Pull-A-Part looking for u-joint axle shafts for this ZJ but they only had one 4X4 ZJ and it didn't have what I needed. They had about 15-20 XJ 4X4s there. If I could find a XJ with the same axle ratio as what I have could I pull the diff from an XJ and put it in my ZJ?
