1996 Sierra 2500
Developed vibration in 4WD. Getting progressively worse. Vibration starts when 4WD engages, then if I shift back to 2WD, it get extremely bad for a few minutes, then stops vibrating completely. Just had it to shop, and they said it was front U-joint. Paid them $300 to change it, and it did not help the problem what-so-ever. The 4WD seems to engage/disengage just fine still, but the vibration is definately getting worse over time. Please help.
