TSB for front end on '11 GT
 

Im sitting at the dealership as I type this. They are replacing the control arms because when I went over a speed bump even at slow speeds I would hear a thunk. It almost sounded like the car was bottoming out. I just wanted to give everyone a heads up.

tsb number?

TSB 11-7-8

I have this same issue on my 2012 gt but it mostly happens when the temp is over 80 lol I tried to schedule a appt. At the dealer,it's pending.

I have this issue on my Boss and have separate thread there. There are a handful of other Boss owners who have the same problem. The dealer couldn't (or wouldn't) reproduce the sound when I took the car in. Thanks for the heads up.

Hey atrain1975,

Let me know if you’d like me to escalate this for you. Just message me with your best daytime number and current mileage.

Hey Anthonynoz,

I’d like to escalate this for you. Could you please message me with your mileage, contact info, VIN, and dealer?

Deysha,

Thanks,

Alex

I did Alex, thanks! I'll get back to you in a little while. :)

Deysha, just sent you a PM - picked up my 2012 on Saturday and have the issue today (500 miles)

Thank you

Thanks rationallo! I received it, I'll get to it in a little bit. :)

Thanks Deysha. I went to the dealer today and they will order the parts - this is the first one they have seen.

I have the same sound and didn't think of getting it checked out before I put my Roush springs on last weekend. Am I outta luck now that I modded my suspension?

Are you experiencing the same suspension problems with the Roush suspension? If so, that ought to help isolate the problematic part(s). What did you swap out aside from springs?

Just the springs. I haven't heard it since the installation but that's probably because I don't go over speed bumps fast now fearing I'll bottom out.

I get the noise going over speed bumps at very low speeds; in fact, the slower the speed, the more pronounced the noise.

That's odd I only noticed when going over at idle speed. I wonder if this is 2 separate issues then..

My 2012 is at the dealer for this issue. They had another 2012 that arrived before mine also with the front suspension clunk. They replaced one of the lower arms on that one and are trying to determine which arm on mine is faulty. Hopefully that solves the problem.

Just so everyone knows, this is not just a Ford thing. My wife's 2009 Passat just had the lower control arms replaced for the same issue. It was also under a TSB from VW. So far, I have not heard the noise on 2011...but, I am listening.

LCAs Replaced
 

Took my car in on Tuesday morning for the 5K oil service and I mentioned the issue I've been having with noises coming from the front end over speed bumps and driveways. The noise seems to occur only when the car is hot and it also warm/hot outside. My service advisor said that they would take a look.

Received a call from my service advisor on Tuesday afternoon and she told me that the lower control arms would need to be replaced. Today is Wednesday and just got the call that my car ready. Hopfully this repair will stop the noises.
