  Q: How to inspect and replace control arm balljoints on Ford Expedition?

  A: Inspect Control Arm balljoints for looseness when separated from the Steering Knuckle. Check if the ballstud can be turned by hand. Replace any loose or easily turned balljoints. To check balljoints with suspension assembled, turn off air suspension system if equipped. Loosen lug nuts, raise and secure vehicle on jackstands. Remove wheels. Use floor jack to slightly raise lower control arm near each balljoint. For upper balljoints, use dial indicator against wheel rim and rock tire to check deflection. For lower balljoints, use dial indicator against wheel rim and prybar between control arm and steering knuckle. If deflection exceeds 0.125-inch, replace faulty balljoint. Balljoint replacement may be possible individually. Check with auto parts store for availability. Use special removal/installer tool to detach and install balljoint. Be careful not to damage rubber boot. Attach steering knuckle to control arm.
