Q: 2005 Z71 Suburban has a slight vibration while accelerating, what could be the cause?

asked by on March 03, 2018

My suburban vibrates slightly while accelerating from take off all the way to highway speeds. Rear seal on transfer case is leaking. There is play in the transfer case shaft vertically but not horizontally. U joints show no play and there is no carrier bearing. What could be the cause of the vibration?

My car has 284000 miles.
My car has an automatic transmission.
