I have been hearing a whinning noise coming from the back end for some time now. The other day I was driving at about 50mph and there was a grinding noise and the tires locked up for a minute. I took apart the differential and removed the driveshaft. The pinion seems to be quite loose and when I put it back together it runs but shakes hard at 25 mph and grinds. There are 3:73 gears in this model and I have an old 1992 with 3:08 gears. Can I swap rear ends without affecting the 4x4 to much? If not how hard is it to replace pinion gear? Are there any specialty tools needed?
have the same problem?
