Your car sounds like a hamster running on his wheel while driving but doesnt make sound at idle or when slowing down to stop what's that noise?

Answer 1

First, remove the tires from the rims to see if a hamster got stuck in there when they were being put on.

Then, check for any brake problems.

Finally, if none of the above helped, check for damaged wheel bearings or driveshaft center bearings or differential bearings (or transfer case on 4WD) until you find something that is not in good condition.

Also note that hamsters (like chipmunks) make a high pitched squeal if you poke them in the nose with a pointed or blunted stick. On the road, you'll usually only get this noise from a Jeep.
