The brake caliper need not be removed to perform this service. Do not twist or stretch the brake hose when moving components.

  1. Remove the cotter pin and nut securing the lower ball joint to the knuckle.
  2.  
  3. Strike the knuckle with a hammer and pull down the transverse link to separate the lower ball joint from the knuckle.
  4.  
  5. Disconnect the tie rod ball joint.
  6.  
  7. Separate the halfshaft from the knuckle by tapping it lightly. If it is hard to remove, a halfshaft removal tool can be mounted on the wheel studs to press the halfshaft from the hub.
