I am just getting used to my used 2001 CVT. Tell me if this is normal. When I go over a rough part of the road, either repaved area where it's been torn up or a pothole or a manhole cover, I get a rattle that seems to come from the right rear wheel area as I go over this. On a straight away road that's smooth I don't have it. Only going over bumps in the road. Is there something under there that gets loose? Or is this just normal with the suspension and the bumps.
