Hi, this is my first post on the wesite. I own a 2000 Pontiac Bonneville SE, with currently 107,000 miles. Around 95K, after new tires, the car started to drive extremely rough over cracks, dips, and holes in the road. I brought it to Pepboys recently and found that the tires were cupping and that I needed new front struts. Now after, new front struts, and new front brakes, the car is driving the same way as before. Any suggestioins?? Also, it feels as though the steering column is loose and vibrates sometimes. Any help is greatly appreciated.
