Models:
2003-2007 Cadillac CTS
Supercede:

Condition
Some customers may comment on a squeak or creak type noise coming from the front of the vehicle. This noise typically occurs while braking or during
slow turns, like parking lot maneuvers.
Cause
The cause of this noise may be due to a worn rear bushing on the front lower control arm rubbing against its outer rate washer.
Correction
Diagnostic Tip
This noise can be isolated, as lubing or wetting the rear bushing will temporarily eliminate the noise. While this noise can be irritating, it poses no
durability or functional concern.
Install an plastic insulating spacer between the rear control arm bushing and the rate washer using the procedure listed below. This plastic insulating
spacer is part of the kit listed below.
Important
Spacers should only be used on old bushings that exhibit the metal-to-metal wear condition as pictured in Step 3. DO NOT use spacers on new
parts or on lower mileage vehicles that do not have this wear condition or a squeak will result due to insufficient clearance.
1. Remove the front lower control arm. Refer to the Lower Control Arm Replacement procedure in SI.
2. Remove the rear bushing rate washer using a punch. Discard the washer.
