Q: Can the Balljoint on the Rear Upper Control Arm be Replaced?
A: The balljoint on the rear upper Control Arm is replaceable. It is a press fit in the arm and requires a hydraulic press and special adapters for removal and installation. It is recommended to take the upper control arm to an automotive machine shop or an auto parts store equipped for such work.
A: With the vehicle on the ground, check for any play in the ball joint grease fitting. Raise the vehicle and support it securely on jack stands, then check for any play in the ball joints by rocking the tire at the top and bottom. If there is any movement, the entire Control Arm must be replaced. The ball joint seal can be replaced by prying off the old seal and pressing a new one into place.
