when vehicle is in motion there is a rattle in rear wheels,especially over bumpy roads,have had vehicle inspected at garage,unable to locate problem.
the exhaust has been tested and made secure.
the garage has repaired or replaced all the problems found except this one,they cannot explain why there is a rattle,
the garage reports there is no danger and no problems with the vehicle,they say it is in very good condition for year.

There is a tool you might be able to borrow or rent from an auto parts store that borrows them called the "Chassis Ear". It is a set of six microphones, a switch box, and headphones. You clip the microphones to suspect points, then drive around while listening with the headphones. You can move the microphones around to zero in on the source of the noise. Be aware that many mechanics have never seen or even heard of this tool. Suspension and alignment mechanics use it to find rattles, squeaks, and other noises.
