Dark Horse Driveline Clunk

[Ford Motor Company]

Hey hope all is well, was there a resolution to this? Same thing is happening tomorrow Darkhorse with roughly 800 miles on it. It went away for a day then came back. Really bizarre. Just dropped it back off at dealer service. They already re tightened the entire suspension at around 400 miles when I first started getting that thunking sound.

Hi there! Will you send us a message with your VIN and your local Ford dealer? I can look into things on my end.

Just curious, I get it when I hit the same bump in the morning right down the street. Then it goes away. First mustang with magnaride. Doesn't happen when I'm driving around the rest of the day?

Also when I put in drive in the morning the rear suspension drops. Ready to launch

Going good bro, hope you’re doing well too. They have changed a bunch of stuff on the car but nothing changed really and don’t have any other car to use when I take to them so I thought I will just hold off for a minute snd see if someone comes up with solution.

My cluck came back at ~2800 miles and after a 300 miles it went away again. Very annoying. In my case, I'm wondering if it could be related to the transmission shfting pattern that happens to create a mechanical resonance.

Is there a way to suspend the transmission learning algorithm adapting to your driving characteristics and stay as is?

Hello everyone, Dark Horse owner from Dubai here. I have a Dark Horse that has a similar noise as the one described in this thread. A few thing I can add to the conversation are that I have a good idea on where the noise is coming from. Firstly I noticed that my noise also happens during light breaking/downshifts/Switching to R after D so this leads me to believe that it is related to the service bulletin Ford had for the previous Mustang. I will be going to my local dealer soon to talk to them about it but I am pretty sure that it's the one I think it is. Hope this helps someone in the future.

Hi. Did you go to the dealer? Any update? Thanks.

This is what i am observing from the various complaints and threads covering this topic.

It sounds like a problem others are having with the transmission output shaft flange. When there is a change in motion between the driveshaft and the trans, the flange on the back of the trans can make a noise due to tolerances in the splines on the trans output shaft and flange. Some have said grease fixes or at least reduces clunk. Other say flange needs to be replaced.

Any thoughts? Not sure if this is an A10 or DH only issue. I have an A10 DH.

Any thoughts?!
The solution is already said in other topics.
Including my own dark horse that had the same problem. I have a shop +20years the first thing i did is what another member said and grease the splines.(hé had the same problem)and i could'nt isolatie the sound. after that no noise. If you stille searching for an official tsb again good luck with that. I already contacted Ford Belgium and for them it's normal they have it with the f150 etc.. And just send customers home with the answer it's normal! Of course we find it not normal and did the search etc... The solution is already given it just depends how much you want to listen. I even gave the part nrs etc.
