#09-03-08-008: Knock Clunk Or Click Noise From Front Suspension Over Small Bumps (Replace Front Lower Control And Caster Arms) -
Attention: This bulletin is intended to correct a condition for front end knock, clunk or clicking. Vehicles previously repaired as part of Campaign #09203A are to follow a different repair procedure as outlined under the Correction section below.
--------------------------------------------------------------------------------
Condition
Some customers may comment on a clunk, knock or click noise from the front suspension over small bumps.
Cause
The rubber "boot" over the front end lower control arm ball joint may have become dislodged or torn compromising the seal. Moisture inside the ball joint seal may cause corrosion, shortening the service life of the component.
Correction
Notice: Before replacing any components under the terms of this bulletin, you must confirm the past service history of the vehicle. Please use GMVIS to confirm if the vehicle was previously repaired under Customer Satisfaction Campaign #09203A. If the vehicle was repaired under this service action, ONLY replace the front control arm found to be the source of the noise and claim the applicable Labor Operation for that part as outlined in SI and the labor time guide.
Vehicles not identified in Customer Satisfaction Campaign #09203A (or not repaired during its duration) and found to have one or more of the rubber boots improperly sealing should have all four front control arms replaced.
