1989 Buick Electra Park Avenue 6 Cyl 3.8L
Just changed the brakes and rotors. But the car is shaking now. What can it be??
Everything is tight. Do you think it is the tires.
Need more information - when does the shaking / vibration occur? Only during braking? If yes, then recheck the wheel bearings / front hub bearing to make sure they are correctly tightened. If tightened OK, then check the front hub / bearing condition for excess play / looseness. Also, check the front suspension bucshings for excess wear / play.
