Removal Procedure

Tools Required

J 43828 Ball Joint Separator

  1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle in General Information.
  2. Notice: Care must be exercised to prevent the drive axle joints from being over-extended. When either end of the shaft is disconnected, over-extension of the joint could result in separation of the internal components and possible joint failure. Drive axle joint boot protectors should be used any time service is performed on or near the drive axles. Failure to observe this can result in interior joint or boot damage and possible joint failure.

  3. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation in Tires and Wheels.
  4. Remove the wiring harness from the lower control arm.
  5. Remove the stabilizer shaft link. Refer to Stabilizer Shaft Link Replacement .
