Rear end howl

[ryancabral86]

Hey everyone, need some help here cause ford won't help. I bought my 07 Stang GT used with 38,000 on it and I just hit 50,000 and ever since about 42,000 I have been hearing a howl in the rear end when making sharp slow turns. Now its possible that it has been making this noise the whole time and I just didn't notice. Ford is trying to tell me that the limited slip differential in my car is known to make those noises and that ford put out a message to expect that. Has anyone else herd of this?

Ford is telling you this or is it the dealership tEcH or SiRvUs mAnAgR? There's no way Ford would ship a mainstream product expected to make noises like that. Ford's "Traction Lok" LSD is not known to make any such noises under normal conditions.

Having issues like this on an 07 with such few miles is very unusual. The first thing I'd do is source a new dealer. Second, I'd have them change the rear-end fluid ensuring they know to add a bottle of friction modifier to the new lube. If that doesn't cure the LSD noise then it'll probably have to come apart for forensic analysis...

If the rear has been unmolested it's possible that Ford's warranty would cover it, no? The dealer dolts may be telling you its normal to wriggle out of that responsibility. If they think its normal then don't allow them to service the car. Clearly they don't know enough about rear axles, hypoid gearsets, plate-type LSDs and so on to be wrenching on one...
