Has anyone on here been successful getting the rear upper shock bolts out with out all of them breaking??? Yes... all four upper bolts snapped. I was using a 3/8 drive ratchet with a 12" extension. I had to drill all of them out and re-tap them. Also, do the seals on the rear axles have a tendency to leak alot?? my left rear brake assy seems to be coated in diff lube. How tough is it to change a seal???
