REMOVAL & INSTALLATION



  1. Raise and safely support the vehicle. Position a jackstand under the engine cradle and lower the vehicle so the weight of the vehicle rests on the jackstand and not the control arms.
  2.  
  3. Remove the tire and wheel assembly. Disconnect the stabilizer shaft-to-control arm bolt.
  4.  
  5. Remove the ball joint from the steering knuckle and the control arm.
  6.  
  7. Remove the control arm mounting bolts and remove the control arm from the engine cradle.
  8.  

Control arm bushing service, if necessary, can only be accomplished by obtaining the proper bushing pressing tools and following the instructions provided with the tools. Attempts to replace the control arm bushings without the presses will result in damage to the bushings, arm, and frame.

To install:

  1. Install the control arm to the engine cradle. Do not tighten the control arm bolts at this time.
  2.  
  3. Install the stabilizer shaft bushings and connect the ball joint to the steering knuckle.
  4.  
  5. Raise the vehicle so the weight of the vehicle is supported by the control arm.
  6.  

The weight of the vehicle must be supported by the control arms when tightening the control arm mounting nuts.

  1. Install the ball joint to the control arm and tighten the nuts to 37 ft. lbs. (50 Nm).
  2.  
  3. Replace the tire and wheel assembly.
  4.  
  5. Raise the vehicle and remove the jackstand.
  6.  
  7. Lower the vehicle.
