  1. Raise and safely support the vehicle.
  2.  
  3. Remove the wheel and tire assembly.
  4.  
  5. Remove disc brake caliper.
  6.  
  7. Remove the dust cap, cotter pin, nut lock, nut and washer from spindle.
  8.  
  9. Carefully slide the hub/rotor from spindle.
    WARNING
    Be careful to prevent inner wheel bearing and seal from contacting spindle threads during removal,

  5. Clean and grease inner and outer wheel bearings.
  6.  
  7. Install inner wheel bearing and new bearing seal.
  8.  
  9. Inspect bearing and seal contact surfaces on spindle for burrs and roughness.
  10.  
  11. Remove all rough contact surfaces from spindle. Apply a coating of lubricant
    WARNING
    Be careful to prevent inner wheel bearing and seal from contacting spindle threads during installation.

  12.  
  13. Carefully slide the hub/rotor onto the spindle. Install outer wheel bearing, washer and retaining nut.
  14.  
  15. Tighten the nut to 30-40 ft. lbs. (41-54 Nm) to preload bearing while rotating the hub/rotor. Stop hub/rotor and loosen nut to completely release bearing preload torque. Tighten the nut finger-tight and install the nut lock. Install a new cotter pin
