I own a 2007 Mustang V6 Pony. I've already had the dealer attempt to fix the problem by replacing both front strut assemblies including the strut bearings at 1200 miles ;-), (great dealer! They gave it a shot and tried to fix it at least and I didn't even buy the car from them.) Covered it under warranty of course.
The problem is an anoying thunking noise coming from the front end suspension when going over small humps or bumps in the road at low speeds. Say 1 to 45 MPH. It's a subtle dull metalic 'thunk' that comes through loud enough to disturb my idea of a quiet ride and anyone who can discern between regular road noise and suspension noise can tell something strange is going on.
I and my mechanic both drove two other pony's and they make the same sound. It seems to me that Ford would or should have set it up so the darn front suspension isn't so bloody loud in the first place as you can hear everything the road has to offer!
It seems that the thunking noise is common even though when you drive a new near 0 miles stang you can hardly hear it, in fact it's not audible at all from what I recall. After a few hundred miles though, thunk, thunk, thunk, thunk,,,every bloody bump or ripple in the road. The thunk isn't real loud but it's noticeable and if you pay attention to it too much it will agrivate the crap out of you. The GT's do it too but it's a bit less noticeable.
Has anyone noticed this thunking sound in their '06 / '07 stangs? I'm really curious as to if you do/did and what you did about it.
I got an 06 and on mine the noise seems to be in the rear or trunk area, it sounds like something is loose, I tried to velcro the spare tire cover cause when I go over a bump, it jumps up and makes the anoying noise. If it does come from the front end, check the body parts, bumper, grill, wheel wells, and even fenders, some body parts are clipped on and they may not be seated properly. Also look at the spacing of the seams ( Gaps) of the body parts to make sure they all are equal( or close to it) any that are not may be hitting. Good Luck!

I also have a thunking noise in my 2006 V6 Tungsten grey coupe that seems to come from the right front. It sounds like the wheel is loose or the shock is not secured. I pointed it out to my wife and she said she could hear it also. Was planning on having the dealer look into it when I take it in for an oil change. Has anyone been able to solve this problem? Is this noise more prominent in cars with the pony package or in coupes over converts? Is there a pattern here somewhere?

When I changed my front swaybar to a GT I didn't torque the swaybar connectors enough to the struts and they made a clunking noise until I went under and re-torqued them to spec. Could be your problem.

Hello gentlemen and ladies if there are any out here ;-). I spent the better part of today at my favorite dealer where I have made friends with some of the mech's and service manager as we all like to tell old autoshop war stories and so on.
I had the stang in today to have my new Ford posi-trac' differential installed on my V6 Pony. While they were at it I went ahead and let them install my new dual exhaust system from Pypes. By the way, Pypes Violater mufflers are droning monsters! The stock muffler has a resonating dampener welded to the exhaust tip. It absorbs and keeps muffler drone from making it's way into the cab of the car! I am going to try getting hold of a couple of them and clamp one to each muffler to see how much it cancels out the drone. I hope it's completely gone and if not, I am going to replace the mufflers with either GT take offs or perhaps I'll try the JBA which I understand are not too shabby and don't offer up drone! GOD I hate that noise!
Okay, while I was hanging out with the guys, the service manager asked me how it's going with the clunking problem. I told him it's still there and I was about to come see him about it so we can get hold of Ford's engineering dept. and see if they are aware of it.
He has to log on to their exclusive dealer only assistance hotline. Waited for him to jump through all the hoops to get to the section where he fills out a form that asks specific questions regaring customer vehicle complaints.
Here's a typed copy of the Q&A. Enjoy and rejoice my friends! Help is on the way! Finally!
**************************
REQUEST FOR DETAILS: DISCRIPTION OF VEHICLE CONCERN: clunking noise over small road deflections at low speeds.
DIAGNOSIS PERFORMED: visual inspection of all suspension components.
PARTS REPLACED: front strut assemblies at earlier service visit.
QUESTION: WERE YOU ABLE TO VERIFY THE CONCERN? ANSWER: Yes
QUESTION: Is there an appropriate pinpoint test in the WSM for this concern? ANSWER: No
QUESTION: Was the pinpoint test followed? ANSWER
TECH'S QUESTION: information to assist in better diagnnosis of concern
HOTLINE RECOMENDATION get off your fat enginering asses and come up with a fix for this friggin problem! < just kidding, I added that ;-). (note, at this point the service manager clicks on send, waits a few seconds and Ford spits out a phone number for him to call. Evidently the number is for the specific person or team addressing this problem at Ford engineering.) Then he's sent a LOG of the call and a summary of their conversation as written below.
CALL LOG:
CALLS TO HOTLINE FOR THIS VEHICLE (he entered my VIN and some other data at the beginning of the hoops)
1/16/07 12:15 PM - TECH SAID: NOISE IN RIGHT FRONT OVER BUMPS AT LOW SPEED. THE STRUTS HAVE BEEN ISOLATED TO NOISE, COMPARES TO OTHER VEHICLES THAT HAVE BEEN TESTED IN THE PAST.
1/16/07 12:15 PM - HOTLINE RECOMENDED: ADVISED DEALER THAT THE ISSUE IS BEING LOOKED INTO AT THE ENGINEERING LEVEL. CONVERTABLE MUSTANGS HAVE ALL THE SAME PARTS BUT DO NOT EXHIBIT THE NOISE, SO THEY ARE EVALUATING THE SUBFRAME CONNECTORS AS A POSSIBLE FIX AS WELL AS THE STRUT MOUNTS. THESE ISSUES HAVE TO BE EVALUATED FOR ROBUST FIX AND CRASH TESTED, SO THE REPAIR MAY NOT BE IMMEDIATELY AVAILABLE, BUT THE FIX IS COMING IN THE FORM OF A TSB OR SSM. THE ISSUE IS NOT STRUCTURAL AND IS ONLY COSMETIC AND IS NOT A SAFETY ISSUE. WAIT FORM MESSAGE TO MAKE REPAIRS. THANK YOU! END OF MESSAGE.
Now I talked with the service manager a bit more analysing what they were saying regarding it only being a cosmetic issue? He said that they consider it so because it's nothing that is dangerous. It is an cosmetic issue because it is only an annoyance issue.
Well that makes sense to me as much as I hate to admit it but they are right. He showed me a blueprint of the subframe to body connections. They are bolts with hard rubber bushings around them with a metal shaft up the middle as with most frame to body bushings on any vehicle. They are small ones, not the huge ones you see on other vehicles.
My theory is that the subframe is flexing to the degree that it allows a tiny bit of side play (normal as that's what the bushings are there for), but the side play is sufficient enough to be a concern or possible cause. The strut bearings are an obvious issue. No need for analyzation. If there is any end play in the bearing i.e. up and down play, it's going to thunk!
That's the story folks. Problem solved....almost! Anyway, I'm happy that Ford is on top of it and we will soon see a TSB out on the issue with the correct and permanent fix!
Look forward to it I'd guess within the next few weeks to few months! Wolfey2k
Hi, Yes I have the same problem too. Under 35mph, small bumps and makes a rattling/thunk noise. It's driving me crazy. I was at the dealer today with no results. I also contacted Ford directly also no results. And I've had this problem since the first day. Brand new 07. I live on a bumpy road so I noticed it right off. I've heard everything from bad upper bearing assembly to bad struts. We need help please.

Have you read the post, info' above your post regarding the TSB that should be coming out pretty soon that will handle the THUNKING problem?
Here’s something that may offer you some comfort. That thunking noise bugs me too. I just talked to the service manager at my dealer today 2-9-07, and he is checking up on the Ford engineering team's progress thus far. Supposedly they have fixed the problem and are running federally mandated crash and safety tests before releasing the fix as a TSB.
Hello folks! Sorry I haven't been keeping this thread updated. But have a look at this thread. http://www.mustangforums.com/m_2297319/mpage_1/key_/tm.htm There are now 16 pages worth of info' for you guys to catch up on. It has evolved into a fairly comprehensive collection of data including pictures and parts blowups. As far as I know, so far, there is a solution to the thunking noise on the horizon! I suppose the other thread above has evolved to the degree it has due to the fact that the title is more what people were searching for regarding this problem. That's why this one has more or less remained static. So have a look and join us there. Wolfey2k

This is the letter I recieved from my delaer today....by the way this is a Mercury Delaer.
Joe, Here is what I have been able to squeeze out of the upper level engineers at Ford. What your Mustang is expieriencing is classified as "strut clacking". You will here the noise under certain driving conditions. Up until now, Ford did not have a clear understanding of what was happening. Ford is now working on the solution for this problem you have been having. Ford is now working on the fix and is testing it to make sure it gets ris of the problem once and for all. I believe they are going to adjust/revise the top of the strut and brace it in a better way to eliminate the clacking noise. I was told today that they are going to relese the "Technical Service Bulletin" in the second quarter. This means they will officially anounce the repair and I am confident that this is what we will do to fix your problem. I have given my service rep your name and vin number so he knows yours is a priority. Hang in there a bit longer and I am sure this issue will be resolved. I have been reading some of the forums you sent me re this issue. I am in your corner on this issue and appreciate your buisness with North Coast Lincoln Mercury.
Thanks for your patience,
Greg Pike North Coast Lincoln Mercury
Take it for what it is worth...but I believe they are close....I only call him twice a week now...lol
Joe

My 07 GT CS 4.0 has had the front end noise since I drove it off the lot. Took it back to the dealer, and they replaced the front right strut (they said it was broken internally). Noise still there. Returned it again after 3000 mi. and they noise miked it again, and now they are replacing the strut and the upper strut mount. They now say the most likely place the noise is coming from is the upper mount. I'll let you know what happens this time. I'm confident that the excess travel noise will still be there, but maybe the low speed rattle will go away.
If any one has not yet heard, Ford's TSB 07-18-2 fixes the clunking and thunking. Got my car back today and if I had been blindfolded would have thought I was riding in a different car. The fix works. I mean to tell you that it is not like riding a magic carpet but about 90% better than it was. Warranty took care of the cost.
