- Support the vehicle in normal driving position with ball joints loaded.
- Wipe the grease fitting and checking surface, so they are free of dirt and grease. The checking surface is the round boss into which the grease fitting is threaded.
- The checking surface should project outside the cover. If the checking surface is inside the cover, replace the lower arm assembly.
REMOVAL AND INSTALLATION
Upper ball joints are not replaceable. The upper ball joint is part of the upper control arm bushing joint and is not serviced separately. If the upper ball joints are found to be defective, the entire upper control arm bushing joint assembly must be replaced.
