Thanks for the replies guys. I called a friend who runs his own shop. We are weighing out rebuild vs installing a whole used unit. I left a message with the best axle guy in town for a quote on a rebuild, and my buddy is going to search his suppliers for a used axle assembly. I think the rebuild will come in cheaper. On my old XJ, I had a quote for a TOTAL rebuild AND trac-lok upgrade come in at around $900 or so. I am not going to upgrade the rear on the ZJ, just want it on the road to get some more life out of it until I can get my situation in order and get a better vehicle for work use. As this ZJ is strictly a work and ****ty weather vehicle.
Thanks again guys.
