NOTE: 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.

Using J 43828 remove the lower ball joint from the steering knuckle. See Special Tools and Equipment .
