Rear End Clunking Noise.....

[BennytheJet]

I drive a manual 2016 Mustang GT with PP. Is it normal to hear a clunking noise in the rear end when there is a sudden change is speed? Whenever I am traveling less than 10 MPH and I pump the brake or release the gas pedal, I hear a clunking sound coming from the rear end. I also hear the noise when I go over a speed bump. The front wheels are quiet, but the rear ones make a louder than normal sound. I took my car in to Ford to take a look at it. They acknowledged there was noise coming from the back, but said it was a loose sub woofer. The car was with Ford for about 2 weeks. The noise is still there.

Before I go back, I would like to know if anyone has experienced this noise and whether or not it's normal.

Thank you,

Mine has the same slop that allows this clunking, did you ever get any help from the dealer?
I took mine in with around two thousand miles on it, was told it was normal, and there was nothing that could be done.
I would really like to know exactly what causes this and if it can be reduced to what I think is normal.
