  1. Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle .
  2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation .
  3. Without disconnecting the hydraulic brake flex hose, remove and support the brake caliper and bracket as an assembly, and remove the brake rotor. Refer to Front Brake Rotor Replacement (With RPO LNF) or Front Brake Rotor Replacement (Without RPO LNF) .
  4. Inspect the head of the wheel stud to be replaced, to determine if the stud is an original, round-head, or a service replacement, D-shape head.
    5. NOTE: It will be necessary to cut off a portion of an original, round-head wheel stud in order to provide clearance to remove the stud from the wheel bearing hub.
  5. If an original, round-head wheel stud is to be replaced, then a portion of the stud must be cut off, so that the remainder of the stud will be approximately 10 mm (0.39 in) long from the face of the bearing hub flange.
  6. Rotate the bearing hub to a position where the least amount of interference between the stud and the steering knuckle exists.
    7. CAUTION: Avoid tool contact to the outer constant velocity boot when removing the wheel bearing mounting bolts. Failure to observe this caution may result in damage to the CV boot.
  7. Using the J 43631  , release the wheel stud from the bearing hub. If a portion of the stud was cut off, remove and discard the stud.
  8. Loosen the 3 wheel bearing/hub assembly mounting bolts evenly, until there is approximately 7 mm (1/4 in) of clearance between the seat of the bearing assembly and the steering knuckle. This will be necessary for removing and installing a service replacement D-shape head stud.
  9. If the stud being replaced was a D-shape head, remove and discard the stud.
