Hey guys, I was wondering if anyone could give me suggestions on helping with the diagnosis of this rattle sound. My car makes a rattle/grinding sound from the rear, even when the car is in park and not moving. The sound sometimes gets louder when moving. The sound is only really noticeable for the first couple minutes of driving it. Anyone have any ideas?

Any help is appreciated. Thanks guys.

 

If it does it when the car is parked, put it up on jack stands, get under there, and figure out what it is. My first GUESS would be exhaust. But check everything, brakes, bolts, shocks, lca's, panhard, lug nuts, everything.
