Adjustment



These front wheel drive vehicles are equipped with permanently sealed front and rear wheel bearings. There is no periodic lubrication or maintenance recommended for these units.

Removal & Installation



  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Remove the front wheel.
  4.  
  5. Remove the front caliper assembly from the steering knuckle by removing the 2 guide pin bolts, then rotating the top of the caliper away from the knuckle and lifting the caliper off the machined abutment on the steering knuckle.
  6.  
  7. Suspend the caliper out of the way with a piece of wire.
  8.  
  9. Remove the front brake rotor from the hub by pulling it straight off of the wheel mounting stud.
  10.  
  11. Remove the hub and bearing-to-stub axle retainer nut.
    NOTE
    This hub nut is a torque prevailing retaining nut and can not be reused. A NEW retaining nut MUST be used when assembling the hub.

  12.  
  13. Remove the 3 attaching bolts that mount the hub and bearing assembly to the steering knuckle assembly.
    NOTE
    If the metal seal on the hub and bearing assembly is seized to the steering knuckle and becomes dislodged on the hub and bearing during removal, the hub and bearing must be replaced. If the flinger disc becomes damaged during the removal procedure, the hub and bearing assembly must be replaced.

  14.  
  15. Remove the hub and bearing assembly from the steering knuckle by sliding it straight out of the knuckle and off the ends of the stub shaft.
  16.  
  17. Gently pry the assembly out with a prybar or tap it out with a soft-faced hammer, if necessary. Be very careful not to damage the hub and bearing assembly.

To install:

  1. Clean the hub and bearing mounting surfaces of dirt and be sure there are no nicks present.
  2.  
  3. Install or connect the following:

    Hub and bearing squarely onto the stub shaft and the steering knuckle
     
    Bearing assembly mounting bolts and tighten equally until the bearing assembly is seated squarely against the front of the steering knuckle. Torque the mounting bolts to 80 ft. lbs. (110 Nm).
     
    New hub and bearing assembly-to-stub shaft retainer nut. A NEW retaining nut MUST be used when assembling the hub. Tighten but do not torque the nut at this time.
     
    Brake rotor and the caliper assembly. Torque the brake caliper guide bolts to 16 ft. lbs. (22 Nm).
     
    Wheel and lug nuts. Torque the lug nuts in a star pattern to 100 ft. lbs. (135 Nm).
     

  4.  
  5. Pump the brakes until a firm pedal is obtained.
  6.  
  7. With the weight on the vehicle on its wheels, apply the brakes to keep the vehicle from moving. Torque the hub and bearing assembly-to-stub shaft retaining nut to 120 ft. lbs. (163 Nm).
    WARNING
    When tightening the hub and bearing assembly to stub shaft retaining nut, do not exceed the maximum torque of 120 ft. lbs. (163 Nm). If the maximum torque is exceeded this may result in a failure of the halfshaft.

  8.  
  9. Inspect the toe setting on the vehicle and adjust, if necessary.
