Oh and to finish it up. I agree with Tuna and others. I'll bet our rute cause is the upper mount & struts. If we don't replace them, we could just weld the whole car up solid and it will still thunk. So I'm going to wait for an answer from Bill Ford. If he's an honest guy and put his foot down and just tell us "yes there's a fix coming xx/xx/07 I'll wait. But if it's a BS answer of "under investagation" again, I'm just going to get some Bilsteins and screw um. I just want a normal car.

Well there have been a few people that mention good luck with some struts. Tokico's and Bistein HD's. I'm sure there might be others.

But that's what others said. I hate to refer items to people that I haven't tried myself.

those struts do they come with their own hardare because i had shocks on my truck installed with smaller bolts by some idiot and it was making the same thunking noise but when i got the right size bolts to fit the shoks struts it all gone.and those struts are they pretty easy to change and will you have to go to get alligment after that

That's one of the problems so far, we haven't found a good replacement upper bearing mount. Steeda makes a good one but it cost $300. I've searched recentlyand no one makes a basic one. I wouldn't mind paying $100/pr but $300 is a lot. I'll have trouble affording the Bilsteins.

Jay, glad to hear on the huge improvement with the swaybar.
I also wanted to let you guys know that my Stang finally came in today and is being prepped for me as we speak, have to go pick it up around 6PM. Anyway, I stopped by earlier just to check it out and I looked underneath and sure enough, mine has the cross member brace mounted on it.....it's an '07 coupe.
Interesting! That's the 2nd report I've see on the cross member being on a delux coupe or GT.

What is your production date? Is it April like the other one that reported that the cross member is there?

Ford must really be paying attention to our issue then since it seem that they are now including the cross member. I bet they are still using the same chepo strut mount though.

Let us know what your production date is would you? That would be great to know.

I'm going to go to a dealer and do some investigation to see if any of their latest production stangs have the cross member.

Vally intalesting indeed!
Okay, on the sticker inside the door jam, it says April 2007.
That would be it right? There isn't like an actual date eg: April 10, 2007....correct?

Hello guys.
New Mustang owner and first post.
I have a 07 GT Premium Coupe. Got it April 18th. It was built in April and does have the cross member!
It only has 200 miles on it. Got it right off the truck with 3 miles on it. So far (knock on wood) no clunking sound.
Great forum, lots of questions answered here.

Okay, well that makes 3!
Thanks for your input 07TGMGT.
3 mustangs probably all built recently, like this past April which means that Ford should be coming out with the TSB very soon!

Why? Well I talked to Howard, my service manager this afternoon. Told him what's up with 'stangs being built as of April as they are coming with the cross member what was previously left out of earlier coupes.

He said "well that makes sense and I would expect that". I asked why. He said "well they always start installing upgrades in production runs first, then they issue a TSB if necessary for previous production runs and in this case they are issuing one I'm sure".

Okay, so that's it. I am going to go to the dealer where I purchased my car late this week or early next as the sales manager says that they have a batch of GT's and V6 coupes coming in the next couple days or so. I'm going to go and look under them and see if they have the cross member. I bet they will if they have a production date of April. I wonder if March production stang coupe'shave them. We'll see!

I should have my newly made cross member installed by tomorrow evening or Friday latest.
Wish me luck!

Wolfey2k

Seems the April production modelcoupesare being sold with the fix for our cars!
Now if only we can get Ford to caugh up the fix!
I am going to see if I can get my service manager to request and get the fix approved now or at least soon since it is now known that the fix is out and in the latest production runs!
Let's hope it works!

I am sure there is more to do than just add the cross member. Like new strut mounts, maybe even completely new strut assembly's.

We'll see.

Some have installed the factory crossbar and done nothing as far as noise. I believe those of us that have the thunking noise have other problems.(strut & upper mount) In my opinion. As I said ages ago, my car had 7.5 miles and had the noise. No support or brace would have stopped that. Only masked or covered up the noise.
Glad to hear you new Mustang owners are fairing out OK. But there are many"thunkers"that have already payed a fortune to Ford that they won't fix. And this is BS.

Hey there. You've asked a lot of important questions, but unfortunately the answers lie in the nearly 1,000 posts to this thread. Every question you ask is either discussed or answered.. . . so untilwe can get a document together that summarizes it all, you're just going to have to read the whole damn thing!!!! There should bea better search engine on this forum so you can go to specific posts, but it doesn't work very well so you may just have to skim through it. The basic answer is that EVERYTHING has been tried and SOME OF IT has worked and SOME OF IT has not worked. It's been pretty much a crap shoot, but stiffening up the suspension with cross members on top and bottom seems to help, and making sure the endlinks are tight and maybe a swaybar with a different angle/heft may also help. Good luck!

They started production of the 07on 06/05/06. Mine was built on 07/27/06the exact date look at your window sticker on the bottom right. I was at the dealer again this morning checking production dates and the upper mount we use(coupe, conv, V6, & GT) is the same as they started with starting 06/04. The strut we 07's use started 06/05/06. They said each Monday the computer info is refreshed. So if someone says the don't thunk after 10/06, I would think they would have new production dates starting then. That doesn't sound right I thought a long while back someone has a thunker made in Dec 06. I agree about that info,(not stepping on anyone toes) but if it was fixed back in Oct. we would have the problem TSB,unless Ford is saying screw us.
Obviously they aren't built in a day but that date is when finished and put the window sticker on and send out the door because I recieved it a couple days later.

Are you talking about a date followed by a bunch of letters and numbers on the bottom right of the windowsticker? That date is different than what is on the sticker inside my door.
