Bulletin No.: 06-03-08-008E

Date: January 15, 2010

Subject: Squeak/Creak Type Noise From Front of Vehicle When Braking or Turning (Install Front Lower Control Arm Rear Bushing Spacer)
Models:
2003-2007 Cadillac CTS

Supercede:
This bulletin is being revised to add the 2007 model year. Please discard Corporate Bulletin Number 06-03-08-008D (Section 03 - Suspension).

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.

Subject: Information on Replacement of Shock Absorbers and Struts Due to Fluid Leaks
Models:
2010 and Prior GM Passenger Cars and Trucks (Including Saturn)
2010 and Prior HUMMER H2, H3
2009 and Prior Saab 9-7X

This bulletin is being revised to add the 2010 model year and Inspection Procedures. Please discard Corporate Bulletin Number 05-03-08-002B (Section 03 - Suspension).

This bulletin is intended to help identify the severity of shock absorber and strut fluid seepage. Improper diagnosis may lead to components being replaced that are within the manufacturer's specification. Shock absorbers and strut assemblies are fluid-filled components and will normally exhibit some seepage. Seepage is defined as oil film or dust accumulation on the exterior of the shock housing. Shock absorbers and struts are not to be replaced under warranty for seepage. Use the following information to determine if the condition is normal acceptable seepage or a defective component.
Important
Electronically controlled shock absorbers (MR) may have a tendency to attract dust to this oil film. Often this film and dust can be wiped off and will not return until similar mileage is accumulated again.

Inspection Procedure
Note
The shock absorber or strut assembly DOES NOT have to be removed from the vehicle to perform the following inspection procedure.

Use the following descriptions and graphics to determine the serviceability of the component.

Shock Absorbers



Do Not Replace shock absorbers displaying condition 1 or 2 levels of seepage.
1. Oil or fluid residue only on the bottom or top of the shock absorber and not originating from the shaft seal (the upper part of the lower shock tube).
2. Light film/residue on approximately 1/3 (a) or less of the lower shock tube (A) and originating from the shaft seal.
Replace shock absorbers displaying conditions 3 and 4 levels of leaks.
3. Oil drip or trail down the lower shock tube and originating from the shaft seal.
4. An extreme wet film of oil covering more than 1/3 (b) of the lower shock tube and originating from the shaft seal.

Coil-over Shock Absorber



Do Not Replace coil-over shock absorbers displaying condition 1 or 2 levels of seepage.
1. Oil or fluid residue only on the bottom of the lower shock absorber tube or the coil-over shock absorber components and not originating from the shaft seal (located at the top of the coil-over shock tube).
2. Light film/residue on the shock absorber tube, but not on the spring seat and originating from the shaft seal.
Replace coil-over shock absorbers displaying conditions 3 and 4 levels of leaks.
3. Oil drip or trail down the lower shock tube and originating from the shaft seal.
4. An extreme, wet film of oil covering the shock absorber tube and pooling in the spring seat and originating from the shaft seal.

Struts



Do Not Replace Struts displaying condition 1 or 2 levels of seepage.
1. Oil or fluid residue only on the bottom of the strut tube or on other strut components and not originating from the shaft seal.
2. Light film/residue on the strut tube, but not on the spring seat and originating from the shaft seal.
Replace Struts displaying conditions 3 and 4 levels of leaks.
3. Oil drip or trail down the strut tube and originating from the shaft seal (located at the top of the strut tube).
4. Extreme wet film of oil covering the strut tube and pooling in the spring seat and originating from the shaft seal.
