1999 GMC Sierra V8 Four Wheel Drive Automatic 100000 miles
Having trouble to identify a clunk in this truck. Truck when stopped and starting up again on pavement feels like slight feeling of tire spin on gravel and then a clunk. Does not do it every time. Also notice the clunk on 2 nd to 3 rd shifts. Many times the shift is smooth and quiet. Even when the truck makes the 'clunk', the shfit is smoot, not jerky. Have new u-joints and cleaned the yoke to ensure it was not sticking. Does not seem to matter if the truck is loaded down (pull trailer) or empty. Can not see anything underneath that shows sign of movement or slippage.
Any thoughts on what I should inspect?
