WARNING
Be careful to avoid over-extending the axle shaft joints. When either end of the shaft is disconnected, over-extension of the joint could result in separation of internal components and possible joint failure. Failure to observe this can result in interior joint or boot damage and possible joint failure.

  1. Disconnect the ball joint from the steering knuckle using separator tool J-29330 or equivalent. For details, see the ball joint removal and installation procedure located in this section.
  2.  
  3. To remove the support assembly with the control arm attached, remove the bolts mounting the support assembly to the car. To remove the control arm only, remove the control arm to support assembly bolts.
