posted previously about deceleration grinding. when i posted it was very bad...now i really have to rev it up and take foot off gas to hear it. everyone i have talked to is perplexed about what is causing this...can anyone help out here??? the other day it happened no matter what speed i was going and every time i let off the gas...there is this grinding and only happens when i take my foot off gas...now it is like it was before when i am at higher speed and take foot off gas pedal to slow down...or if i step on it hard and let off.

 

does it do it while parked? how loud is it? is it distinctly metal on metal like bad brakes? or is it more of just a vibration? do you have a manual transmission?
