13-7-8 GRUNT/CREAK/CHIRP/SQUEAK NOISE FROM THE FRONT LOWER CONTROL ARM OVER BUMPS
Publication Date: July 15, 2013
FORD: 2011-2014 Mustang
The article supersedes TSB 12-8-24 to update the model years, Service Procedure and Part List.
ISSUE:
Some 2011-2014 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.
ACTION:
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
Attach Rotunda wireless chassis ears (JSP97202) or equivalent on both 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. Due to hydraulic fluid flow some noise from the bushing is normal. There would typically be some difference from side to side on a unit with a noisy control arm.
If the noise is not confirmed as coming from the hydro bushing, this article does not apply, refer to Workshop Manual (WSM), Section 204-00 for normal diagnostics.
If the noise is confirmed as coming from the hydro bushing, replace the affected lower control arm with the new lower control arm with shield and 3 screws. Tighten the three (3) shield screws to 7 N-m (62 lb-in.) Refer to WSM, Section 204-01. (Figure 1)

Well, the other day as my 5.0 clicked over its first 3400 miles or so I hear a bang, which I assumed was someone else's car and soon after I hear a clanking, grinding racket coming from the front drivers side wheel area of my new 2013 Mustang! I'm thinking Ford is still using crap Chinese sourced coils/ struts etc that they used in my wifes 2000 Taurus which over the years went back to Ford 3 times for broken suspension parts and silent recalls. My hope is the dealership doesn't try to give me any grief because I'd installed Ford Racing Boss 302 Laguna Seca wheels with tires that match factory specs for that car or my C&L CAI with no tune or my Roush AB exhaust. Wherever you are Ford rep person, I may need your intervention again!! Cheap fragile suspension parts (if that's what it is) on a vehicle with this much power is a big NO NO IMO.
I received your PMs. Please send me VIN and dealer so I can get this escalated for you.

UPDATE: Got the TSB service for the noisey front end done last week. Havent driven the car much as I've been busy at work but so far, the problem seems solved. Cant say enough about the great help FordService has been in getting the work done as quickly as possible given that the parts needed to do the job were on nationwide backorder.
