    Upper Ball Joint

    Print

    INSPECTION



    Before performing any ball joint inspection, make sure that the wheel bearings are adjusted correctly and that the control arm bushings are in good condition.

    1. Make sure the vehicle is parked on a level surface.
    2.  
    3. Raise and support the front of the vehicle safely with jackstands. Place the jackstand under each lower control arm as close as possible to the lower ball joint. Make sure that the vehicle is stable and the control arm bumpers, if equipped, are not contacting the frame.
    4.  
    5. Wipe the ball joints clean and check the seals for cuts or tears. If a seal is cut or torn, the ball joint MUST be replaced.
    6.  
    7. Check the ball joints for horizontal deflection (looseness):
      1. Position a dial indicator against the lowest outboard point on the rim.
      2.  
      3. Grasp the tire (top and bottom), then pull outward on the top and push inward on the bottom; record the reading on the dial indicator.
      4.  
      5. Grasp the tire (top and bottom), then pull outward on the bottom and push inward on the top; record the reading on the dial indicator.
      6.  
      7. The difference in the dial indicator reading is the horizontal deflection of both joints. If the reading exceeds 0.125 in. (3.2mm), the lower ball joint should be checked for wear in order to determine what component(s) must be replaced.
      8.  
      9. With the vehicle still supported by jackstands, place a dial indicator against the spindle in order to measure vertical movement.***WARNING***DO NOT pry between the lower control arm and the drive axle seal or damage to the seal may result.
      10.  
      11. Pry between the lower control arm and the outer bearing race while reading the dial indicator. This reading will show vertical deflection (looseness).
      12.  
      13. The lower ball joint is not a pre-loaded joint and may show some looseness, but it should be replaced if movement exceeds 0.125 in. (3.2mm).
      14.  
      15. If necessary, disconnect the upper ball joint from the steering knuckle.
      16.  
      17. Check for any looseness or if the stud can be twisted by hand. If so, the joint should be replaced.

    1. Raise and support the front of the vehicle safely on jackstands.
    2.  
    3. Remove the tire and wheel assembly.
    4.  
    5. Remove the brake caliper and support it from the vehicle using a coat hanger or wire. Make sure the brake line is not stretched or damaged.
    6.  
    7. Remove the lower shock absorber through-bolt, then remove the shock from the lower mount. If equipped with front torsion bars, release the tension from the bar, then remove the torsion bar and place aside.
    8.  
    9. Remove the cotter pin and retaining nut from the upper ball joint.
    10.  
    11. Position a suitable ball joint separator tool between the upper joint stud and the steering knuckle. Use the tool to separate the upper ball joint from the steering knuckle. Pull the control arm free of the steering knuckle after removal.
    12.  

    After separating the steering knuckle from the upper ball joint, be sure to support the steering knuckle/hub assembly to prevent damaging the brake hose.

    1. Remove the retainer nuts, bolts and washers securing the ball joint to the upper control arm.
    2.  
    3. Clean and inspect the steering knuckle hole. Replace the steering knuckle if the hole is out of round.
    4.  

    To install:
    1. Position the joint in the upper control arm, then install the joint retaining nuts and bolts. Position the bolts threaded upward from under the control arm. Tighten the ball joint retainers to 19 ft. lbs. (25 Nm).
    2.  
    3. Remove the support from the steering knuckle, then install the ball joint to the knuckle. Make sure the joint is seated properly, then install the stud nut and tighten to 75 ft. lbs. (97 Nm) for vehicles through 1986 or to 98 ft. lbs. (127 Nm) for 1987-96 vehicles. Install a new cotter pin.
    4.  

    When installing the cotter pin, never loosen the castle nut to expose the cotter pin hole.

    1. Reposition and secure the brake caliper.
    2.  
    3. Install the tire and wheel assembly.
    4.  
    5. Remove the jackstands and carefully lower the vehicle.
    6.  
    7. Check and adjust the front end alignment, as necessary.

    1. Raise and support the front of the vehicle safely by placing jackstands securely under the lower control arms. Because the vehicle's weight is used to relieve the spring tension on the upper control arm, the jackstands must be positioned between the spring seats and the lower control arm ball joints for maximum leverage.
    2.  


    CAUTION
    With the components unbolted, the jackstand is holding the lower control arm in place against the coil spring. Make sure the jackstand is firmly positioned and cannot move, or personal injury could result.

    1. Remove the tire and wheel assembly.
    2.  
    3. Remove the brake caliper and support it from the vehicle using a coat hanger or wire. Make sure the brake line is not stretched or damaged and that the caliper's weight is NOT supported by the line.
    4.  
    5. Remove the cotter pin and retaining nut from the upper ball joint.
    6.  
    7. Position J-23742 or an equivalent ball joint separator tool between the upper joint stud and the lower joint/control arm. Use the tool to separate the upper ball joint from the steering knuckle. Pull the steering knuckle free of the ball joint after removal.
    8.  

    After separating the steering knuckle from the upper ball joint, be sure to support the steering knuckle/hub assembly and anti-lock brake sensor wire, if equipped to prevent damaging the brake hose and wiring.

    1. Remove the riveted upper ball joint from the upper control arm:
      1. Drill a 1 / 8 in. (3mm) hole, about 1 / 4 in. (6mm) deep into each rivet.
      2.  
      3. Then use a 1 / 2 in. (13mm) drill bit, to drill off the rivet heads.
      4.  
      5. Using a pin punch and the hammer, drive out the rivets in order to free the upper ball joint from the upper control arm assembly, then remove the upper ball joint.
      6.  

    2.  
    3. Clean and inspect the steering knuckle hole. Replace the steering knuckle if the hole is out of round.
    4.  

    To install:
    1. Position the joint in the upper control arm, then install the joint retaining nuts and bolts. Position the bolts threaded upward from under the control arm. Tighten the ball joint retainers to 17 ft. lbs. (23 Nm).
    2.  
    3. Remove the support from the steering knuckle, then install the ball joint to the knuckle. Make sure the joint is seated, then install the stud nut and tighten to 61 ft. lbs. (83 Nm). Install a new cotter pin.
    4.  

    When installing the cotter pin, never loosen the castle nut to expose the cotter pin hole.

    1. If not installed already, thread the grease fitting into the ball joint. Use a grease gun to lubricate the upper ball joint.
    2.  
    3. Reposition and secure the brake caliper and anti-lock brake sensor wire.
    4.  
    5. Install the tire and wheel assembly.
    6.  
    7. Remove the jackstands and carefully lower the vehicle.
    8.  
    9. Check and adjust the front end alignment, as necessary.
