TECHNICAL
Bulletin No.: 09-03-08-008A
Date: May 26, 2010
Subject: Knock, Clunk or Click Noise from Front Suspension Over Small Bumps (Replace Front Lower Control and Caster Arms)
Models:
2008-2009 Pontiac G8
Attention:
This bulletin is intended to correct a condition for front end knock, clunk or clicking. Vehicles previously repaired as part of Customer Satisfaction
Program 09203A are to follow a different repair procedure as outlined under the Correction section below.
Supercede:
This bulletin is being revised to update the Parts Information. A front lower control arm kit is now available that services all four lower control arms as
outlined in this Service Bulletin. Please discard Corporate Bulletin Number 09-03-08-008 (Section 03 - Suspension).
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 (dealers
using WINS) or the Investigate Vehicle History link (dealers using GWM) to confirm if the vehicle was previously repaired under Customer Satisfaction
Program 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 Program 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.
Front Lower Control and Caster Arm Replacement (Both Sides)
The instructions below detail replacement of all four front lower control and caster arms.

supported by a hoist, support the vehicle with jack stands at the opposite end from which the components are being removed and strap the
vehicle to the hoist.
1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in SI.
2. Remove the front wheels. Refer to Tire and Wheel Removal and Installation in SI.
