I bought a 2006 Pontiac Grand Prix GT with 55,000 miles on it.. I have this annoying vibration felt in the steering wheel and a few other symptoms.
1. Small Pop noise when going from Park to Reverse
2. Vibration in Steering wheel Felt at all speeds, I thought it was coming from the drivers side
3. If I am on an incline put car in Reverse and hit the Gas, I feel a thump, which I think is coming from my Downpipe hitting the body.
Sofar I replaced
1. Drivers Side Wheel Bearing
2. Drivers Side Half Shaft
3. Switched tires from Front to Rear
4. Lubed Steering shaft, got rid of my turning thump
I am trying to figure out if itd my Motor Mount or my Ball joints and Bushings.
HELP, I don't Feel like spending anymore money without a good source of where the problem is...
