Ford has just recently issued 2 TSBs for the 05 GT Mustangs. The first one is TSB 04-24-20 : The issue is limited slip axle chatter during low speed manuevers while turning. Its refers to replacing the clutch pack and using different gear lube. This TSB also covers other Ford models with limited slip rear diffs. The second one is TSB 04-26-22 : The issue is for "check engine" light illumination without driveability concerns and multiple DTCs P035X's. This is set during engine decell and would probably not be noticed during driving. The P035X DTC are for the ignition coil packs primary or secondary circuits malfunction.
I got this from AFM.

 

Here is a full list that includes the ones above.

Can someone please give me a better definition of what this rear end chatter sounds like? I just noticed some kind of sound from the rear and I don't know if this might be the cause of it. To me it sounds like a small popping noise, I guess a more technical term could be chatter..... I am taking it in to dealer tomorrow and I don't know what to tell them if it doesn't make the sound tomorrow.

 

Well I know I read a post that said something like there was a problem related to a weld in one of the rear quarter panels that allowed for the sheet metal to make a slight popping sound. Not sure on rear end noise, dont have mine yet, but soon.
