This forum is great . Just bought a 94 suburban k1500 4x4 with 172000 on here runs great drive smooth last night. Needs little things here and there but the big one is the short (drivers side front 1/2 axle) where it bolts to the front dif is leaking. also if you give a jerk to the output shaft/flange coming out of the diff it is loose. the book does not really say much on this. can any one help? sorry if there are post about this that I did not read yet.
