Rattle/Creak/Popping Type Noise from Front of Vehicle When Turning (Replace Both Front Stabilizer Shaft Insulator Brackets)
2002-2003 Chevrolet Cavalier
2002-2003 Oldsmobile Alero
2002-2003 Pontiac Am, Grand Sunfire
with FE1 or FE2 Suspension
Condition
Some customers may comment on a rattle/creak/popping type noise coming from the front of the vehicle when turning the steering wheel. This noise can typically be duplicated with a short drive on uneven road surfaces, then turning the vehicle left or right into a 90 degree turn.
Cause
This condition may be caused by the front stabilizer shaft insulator to front suspension crossmember brackets being out of specification. Using the J 39570 Chassis Ear hooked up to each bracket may assist in determining if they are the source of the noise.
