Ok i have a 94 Buick regal. i feel that the front drivers side strut cartridge went out. Im saying this because the ride is terrible from what it was before. at speeds over 50 the steering wheel shakes and that side of the car shakes. also when i turn left i hear like a rubbing sound. I was just wondering if the cartridge is the problem here...for the ride anyway. what do you think the rubbing noise is related to?
