  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Place jack under lower control arm, then raise the jack slightly.
  4.  
  5. Remove or disconnect the following:

    Tire and wheel assembly
     
    Brake caliper and position it to the side
     
    Cotter pin and the lower ball joint retaining nut. Using the proper tool separate the ball joint from its mounting. Support the knuckle assembly so its weight will not damage the brake hose.
     
    Ball joint out of the lower control arm, using tool J-9519-30-D or equivalent.
     

  6.  

To install:

  1. Start the new ball joint into the control arm. Position the bleed vent in the rubber boot facing inward.
  2.  
  3. Install or connect the following:

    Ball joint into the control arm until fully seated
     
    Lower ball joint stud into the steering knuckle
     
    Brake caliper, if removed
     
    Ball stud nut. Torque the nut to 90 ft. lbs. (122 Nm) plus the additional tighten necessary to align the cotter pin hole. Do not exceed 130 ft. lbs. (175 Nm) or back the nut off to align the holes with the pin.
     
    New lube fitting and lubricate the new joint.
