Squeak, Rattle, Pop or Clunk Noise from Front of Vehicle During Suspension Movement (Replace Front Stabilizer Shaft Insulators)

This bulletin is being revised to add model years, update the service procedure and add part numbers. Please discard Corporate Bulletin Number 04-03-08-003A (Section 03 -- Suspension).

Some customers may comment on a squeak, rattle, pop, or clunk noise coming from the front of the vehicle during suspension movement.

This condition may be caused by the interface between the front stabilizer shaft, the front stabilizer shaft insulators (bushings) and the front stabilizer shaft mounting clamp.

Verify the customer comments. Then replace the front stabilizer shaft insulators (bushings), if necessary, following the procedure outlined in this bulletin.

1. Verify the customer comment. Use Chassis Ear (SA9217NE or J39570 ) or similar tool to determine the source of the noise. Refer to Noise Diagnosis - Front Suspension in SI.
2. If the noise is coming from either the front stabilizer shaft insulators (bushings) or the clamps:

Important: Check the Service Parts Identification label in the rear compartment (trunk) to determine the vehicle's suspension system type, then obtain the correct insulators (bushings) corresponding to that suspension system type.

•	On vehicles built after VIN breakpoint 4Z125195, replace both front stabilizer shaft insulators (bushings). Refer to the Stabilizer Shaft Insulator Replacement procedure in the Front Suspension sub-section of SI.

•	On vehicles built up to and including VIN 4Z125195, replace the front stabilizer shaft insulators (bushings) and clamps. Refer to the Stabilizer Shaft Insulator Replacement procedure in the Front Suspension sub-section of SI.

3. Verify the repair by repeating Step 1.

For vehicles repaired under warranty, use:

If another procedure is performed, refer to the appropriate Electronic Labor Time Guide for the correct Labor Operation Code and Time.
