- GRUNT/CREAK/CHIRP/SQUEAK NOISE FROM THE FRONT LOWER CONTROL ARM OVER BUMPS
FORD: 2011-2013 Mustang
The article supersedes TSB 11-10-17 to remove the production fix date, update the model years, Service Labor Time Standards and Part List.
Some 2011-2013 Mustangs vehicles may exhibit a grunt/creak/chirp/squeak noise from the front lower control arm hydro bushing. These noises may occur over large vertical bumps like speed bumps, pot holes, rough roads and driveway approaches.
Follow the Service Procedure steps to correct the condition.
- Use chassis ears on the lower control arm hydro bushing bracket tabs to verify noise is coming from the hydro bushing. The hydro bushing is the large diameter bushing at the rear of the control arm.
- If the noise is not confirmed as coming from the hydro bushing, do not continue with this article. Refer to Workshop Manual, Section 204-00 for normal diagnostics.
- If the noise is confirmed as coming from the hydro bushing, replace the lower control arm that is making the noise. Refer to WSM, Section 204-01.
