OK here is the TSB for the hesitation problem

TSB 06-9-9

The TSB for the rear end moan is 06-12-11. While I have yet to find the actual pdf here is a link to TSB 05-20-2 which says "rear axle moan for 05's and 06's". I don't know if the underlying fix or problem is the same but print it out, write 06-12-11 on it and take it to your dealer and have them look up 06-12-11.

TSB 05-20-2

Thanks for the TSBs WingerWV. They say 2005 - 2006, do they apply to 2007 as well? I see that jkilgor with a 2007 had the clutchpacks replaced. I really haven't noticed anything yet. I only have about 500 miles on my 2007.

Not a problem. Interestingly enough I found a thread in another forum on here where guys are getting the moan fixed by replacing the rear end fluid and not having the clutch packes replaced at all.

Oh great! I can hear the noise now. First time today I noticed it. I had the windows down, no radio and was doing a slow uturn in a shopping center. I was like, "what is that noise" So I went to a more empty part of the lot to do a few more and it was loud and clear. Almost sounded like a animal howling under its breath. You gotta go real slow in the unturn to hear it.

I still have not seen anyone post the TSB for this. I have seen the 05-20-2 one but the description did not seem to apply.
If someone has this specific TSB would you please post it. Much easier to have it in hand then try to talk to them about clutch packs when I dont even know what a clutch pak is.

Will call to set an appointment but would like to read the TSB first.

I have been hearing something coming from the back of my car, I thought I might not have tightened a bolt all the way installing my SLP's. I went back under there and checked everything out and it was fine. So im thinking this may be my problem too. When I take it into the shop should I take off my CAI and reflash to stock?

Your choice. Some say do it, others (me included) say do not. I asked this when I first joined a few months ago and decided not to when I go in for service. Have not had any problems from my dealer about it. I hear some dealers are jerks though.

They cant blame a problem regarding my rear differential on my tune logically. So I see no reason to reflash.

I scheduled last Friday and had an appointment with the dealer today. They had my car from 9:00 to 5:30. I was unaware of the tsb [:@]. They told me there is a known problem with the clutch pack. They said the factory's torque setting on the pack was 800 lbs. The only approved fix is to loosen the torque on the clutch pack which would effectively disable the limited slip thus eliminating the noise. "All mustangs make that noise. When they designed the differential it was supposed to get an additive to stop the noise, but it didn't work". Basically what I was told was.......either deal with the noise
OR lose limited slip. Sounds really stupid to me that I just accepted what I was told. I mean, I bought a performance car with a limited slip differential that didn't make that noise for a long while. Mine started around 10,000 miles. It's really loud now. Of course they followed it all up with...."you have lots of warranty left if it tears up we'll just replace it. Is my dealership's service department just lazy?
