  1. Raise the vehicle and support the frame with jack stands. Refer to Lifting and Jacking the Vehicle in General Information.
  2. Remove the tire and wheel assembly. Refer to Wheel Removal in Tires and Wheels.

    3. Object Number: 161259 Size: SH
  3. Remove the Road Sensing Suspension position sensor from the lower control arm.
  4. Remove the ball joint from the knuckle.
  5. Drill out three rivets retaining ball joint starting with a 1/4 inch drill bit and finishing with a 1/2 inch drill bit.
  6. Remove the joint.

Installation Procedure

    Object Number: 161266 Size: SH
  1. Install the new ball joint (4) into the control arm (6).

    2. Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  2. Install the ball joint to control arm bolts.

    3. Tighten

        • Tighten the ball joint to control arm nuts (5) to 68 N·m (50 lb ft).
        • Tighten the ball joint nut (2) to 10 N·m (84 lb in) using J 35551 90 degrees to torque wrench. Tighten the nut an additional 120 degrees. When tightening the nut a minimum torque of 50 N·m (37 lb ft) must be obtained. If 50 N·m (37 lb ft) is not obtained, inspect the ball joint for stripped threads. If threads are satisfactory, replace the ball joint and knuckle. If required, turn the nut up to an additional 60 degrees in order to allow for the installation of the cotter pin (1).

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified.

    4. Tighten

        • Tighten the ball joint to control arm nuts (5) to 68 N·m (50 lb ft).
        • Tighten the ball joint nut (2) to 10 N·m (84 lb in) using J 35551 90 degrees to torque wrench. Tighten the nut an additional 120 degrees. When tightening the nut a minimum torque of 50 N·m (37 lb ft) must be obtained. If 50 N·m (37 lb ft) is not obtained, inspect the ball joint for stripped threads. If threads are satisfactory, replace the ball joint and knuckle. If required, turn the nut up to an additional 60 degrees in order to allow for the installation of the cotter pin (1).
  4. Install the Road Sensing Suspension position sensor to lower control arm.
  5. Install the tire and wheel assembly. Refer to Wheel Installation in Tires and Wheels.

    6. Tighten
    Tighten the wheel nuts to 140 N·m (100 lb ft).

  6. Lower the vehicle.
