I was wondering if anyone has experienced this type of noise. When for example I enter my driveway and the rear axle goes through the dip, it sounds as if there is loose metal parts clanging against each other. Back description perhaps, but dont know how else to explain. the noise only comes from the back end and seems like it is from the drivers side. Any thoughts?

Could it be a loose muffler connection??

 

Try to get the car on a lift and see if any of the muffler mounting bolts need tightning. Pretty easy fix with the right size wrench.
