Never heard a noise like this on a car....
When I first fire up the Mustang, there is a fast, loud rattle from the rear end for a few seconds, which then goes away. Revving the motor doesn't create this noise again.
Then, during my first turn while driving, the noise comes back, just as intensely as before. As the car warms up, it usually goes away, but might come back later during another turn.
If the car is warm, it doesn't make the noise at startup.
The sound can best be described as a very fastly repeating, hollow sounding rattle. If you put a golf ball in a big empty plastic water jug and shook it real fast, you'd get this noise. It sounds similar to a blown strut, but faster.
I have no idea what it is. My differential seems fine, the rear shocks are A-okay, the exhaust system is as secure as it will ever be, and I don't think it's the U-joint because they usually sound differently when they're going.
Any suggestions?
