problem #1

GTO 8-cyl

I have 14000 miles, and had a vibration from 55 to 70 for months. I took vehicle to the dealer a couple times, and they said they could not reproduce the problem. The driveshaft bolts came loose or sheared off at the differential 3 separate times. The first 2 times the dealer tightened or replaced the bolts, and it still has not solved the problem. Also, it caused the pinion seal to leak, which the dealer replaced under warranty. I am a mechanic, and put the car in the rack to inspect it. The driveshaft was not running, causing the bolts to vibrate loose and shear off. This could be very dangerous if the driveshaft comes off. I did not feel safe driving this car, and am contacting Pontiac about replacing the driveshaft. I knew of several other owners who have had this problem.
