Fig. Fig. 1: The hub and bearing are pressed out of the steering knuckle

  1. Remove the steering knuckle.
  2.  
  3. To remove the hub, support the knuckle assembly in an arbor press with the hub facing down.
  4.  
  5. Use a proper size arbor that will fit through the bearing and press the hub out.
  6.  
  7. If the inner bearing race stayed on the hub, clamp the hub in a vise and use a bearing puller to remove it.
  8.  
  9. On the knuckle, remove the splash shield and internal snaprings from the bearing housing.
  10.  
  11. With the knuckle in the same pressing position, press the bearing out.
  12.  
  13. Clean the bearing housing and hub with a wire brush, then inspect all parts. Replace parts that have been distorted or discolored from heat. If the hub is not absolutely perfect where it contacts the inner bearing race, the new bearing will fail quickly.
  14.  

To install:
  1. The new bearing is pressed in from the hub side. Install the snapring and support the steering knuckle on the press.
  2.  
  3. Using the old bearing as a press tool, drive the new bearing into the housing up against the snapring. Make sure the press tool contacts only the outer race of the bearing.
  4.  
  5. Install the outer snapring and splash shield.
  6.  
  7. Support the inner race on the press and drive the hub into the bearing. Make sure the inner race is supported or the bearing will fail quickly.
  8.  
  9. Install the steering knuckle, then carefully lower the vehicle. BE SURE to torque the axle nut correctly before allowing the vehicle to roll.
