Tools Required
^ J43828 Ball Joint Separator

Removal Procedure

Notice: Use only the recommended tools for separating the ball joint from the knuckle. Failure to use the recommended tools may cause damage to the ball joint and seal.

1. Raise and support the vehicle. Refer to Vehicle Lifting.
2. Remove the tire and wheel.
3. Remove the stabilizer shaft link.





4. Remove the cotter pin (1).
5. Loosen the lower ball joint retaining nut (2) from the ball stud.

Notice: Care must be exercised to prevent Tri-Pot joints from being over-extended. When either end of the shaft is disconnected, over-extension of the joint could result in separation of internal components and possible joint failure. Drive axle joint seal 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 seal damage and possible joint failures.
