I have a '99 Bonneville with a vibration in the wheel above 60 miles an hour. I replaced the front tires and had all 4 wheels balanced, twice. I had this work done by a local independant tire shop and the Pontiac dealer. Both have always given me great service in the past. It still has this vibration and it is beginning to drive me to vibrate, too. The dealer tells me to take it to a tire shop that has a force drive balancer? Claims it can check the balance on the car and pinpoint the problem between the wheels, tires, or not. This costs about $120 bucks in my area.
Does anyone have any ideas?
