REMOVAL & INSTALLATION



Vehicles equipped with 13 inch tires have a 4 stud wheel mounting system. Vehicles equipped with 14 inch tires will have either a 4 or 5 stud wheel mounting system.

With Disc Brakes

See Figures 1 and 2


WARNING
If a wheel lug stud needs to be replaced, do NOT try to hammer the stud out of the hub/bearing. If the stud is removed by hammering it out, you can cause damage, leading to bearing failure.

  1. Raise and support the appropriate end of the vehicle safely using jackstands, then remove the wheel.
  2.  
  3. Remove the brake pads and caliper. Support the caliper aside using wire or a coat hanger. For details, please refer to Brakes of this guide.
  4.  
  5. Lift the rotor off the studs.
  6.  
  7. Install a lug nut on the wheel stud requiring removal, so the threads on the stud are even with the end of the lug nut. Rotate the hub so the stud requiring removal is aligned with the notch cast into the front of the steering knuckle. Install a suitable C-clamp and adapter removal tool, Special tool C-4150 or equivalent, on the hub/bearing flange and wheel stud.
