GRUNT/CREAK/SQUEAK/CHIRP NOISE FROM THE TSB 07-23-1 LOWER CONTROL ARM BUSHING OVER BUMPS— BUILT BEFORE 2/28/2007 |
2005-2007 Mustangs 4.0L/4.6L with a build date before 2/28/2007 may exhibit a grunt/creak/squeak/chirp noise from the lower control arm (LCA) hydro bushing over bumps like speed bumps, pot holes, rough roads, and driveway approaches.
SERVICE PROCEDURE
- Use chassis ears on the LCA hydro bushing bracket tabs to verify noise is coming from the LCA Bushing.
- If noise confirmed, then proceed to step 2.
- If not, then this does not apply. Proceed with normal Workshop Manual (WSM) diagnostics.
- Replace LCA with latest level parts.
