Upper Control Arm: Description
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
An upper control arm is attached to the top of each rear knuckle, connecting the knuckle to the rear suspension crossmember.
The attachment of the upper control arm to the knuckle is achieved through a ball joint in the upper control arm. The upper control arm is bolted to the rear suspension crossmember using a pivot bar which is rubber isolated from the upper control arm.
