sorry if this was posted somewhere else. anyway there is a rattle when starting off slow. its coming from the rear passenger wheel area. As the car starts out the clunking gets faster and it doesn't stay consistent with the spin of the tires just a gradual rattle. After 40-45 MPH it stops as if centrifugal force causes it to stop. It rattles and clunks when going over bumps and railroad tracks. It's a metallic rattle. I've looked underneath the car and to me it looked fine. The car steers fine and does not vibrate at all. It doesn't rattle in reverse or braking unless you hit a bump. Any help is useful thank you.
