REPLACEMENT



  1. Raise and support the vehicle safely using jackstands.
  2.  
  3. For front suspension stud replacements, remove the wheel hub and bearings. For details, refer to the wheel bearings procedure later in this section or the brake disc procedure in of this guide.
  4.  
  5. For rear suspension stud replacements, remove the axle shaft from rear axle assembly.
  6.  

On some applications it may be possible to replace a rear axle hub stud without removing the axle shaft. In order to accomplish this, carefully knock or press out the damaged stud. Insert the new stud into the hub, then use the flat side of a lug nut and some washers (to protect the outside of the hub) to draw the stud into position in the hub.

  1. Support the disc or shaft hub in a hydraulic press, then press out the damaged stud. If a press is not available, a hammer and suitable driver may be sufficient, but extreme care should be taken not to damage the hub.
  2.  

To install:

  1. Insert the new serrated stud into the disc or shaft hub, then use the press to push the stud into position. If a press is not available, use a washer and the lug nut (installed with the flat side toward the washer) to draw the stud into position by tightening them down on the hub.
  2.  
  3. Install the brake disc and wheel bearings or the rear axle shaft, as applicable.
  4.  
  5. Remove the supports and carefully lower the vehicle.
