I have a 2005 mustang and it is making some weird noise. After bringing it into the shop the first time they replaced the throwout bearing and the noise stopped for a month, then returned. I took it in again and they replaced the clutch plate?? After them having it for 3 WEEKS and me having to drive a FOCUS....it is making the noise again. It's hard to describe the noise, but it only does it when it's cold, and I am letting the clutch out, usually on a hill, even a slight incline??? They are stumped....anyone else have this problem??

 

does it feel almost like a slipping for something. mine started a strange thing lately where it makes almost a thuding and slipping feeling. only noticed it in cold and at the end of the clutch in first..

 

No not a slipping, I don't think....it's more of just a noise....I would describe it almost as sounding like a fog horn. As a matter of fact, someone was riding in my car with me and thought someone was honking at us??

 

doubt this helps, but on my moms old 91 5.0, we would get almost a horn sound coming from one of the wheel bearings... The models are vastly different so I doubt it's the same issue.
