GMC Safari Vibration
Question:
I have a ‘92 GMC Safari AWD. This things has a vibration around 50 -75 mph, have replaced both ujoints in rear driveline, replace front driveline, 5 sets of tires, trans mount, left front axle, with no improvement. I have taken the front driveline out and vibration is gone, maybe balance driveline in the van? Also, now with front
Response:
Send both prop shafts out for balance.

Response:
Thanks, but already had rear driveline balanced, and front is new and should be balanced….(right?). I did notice this afternoon, on the new driveline there is punch mark on one the bolt holes, and also one on the flange on the vehicle, maybe we should try matching them up?. – Hide quoted text — Show quoted text – > Send both prop shafts out for balance. > I have a ‘92 GMC Safari AWD.
