Position: Rear upper.

A control arm links the wheel assembly to the vehicle's chassis. It lets the wheel move up and down while holding it in its intended position. Worn or bent arms can cause clunking over bumps, vague or wandering handling, or uneven tire wear. Other suspension parts can cause the same symptoms, so inspect the rear suspension before replacing. If the original rear upper arm is the cause, this arm replaces it. Have the wheel alignment checked after installation.
