Removal & Installation




NOTE
Whenever the hub or bearing assembly is removed, the wheel bearing assembly must be replaced. Never reuse the old bearing assembly.

  1. Before servicing the vehicle, refer to the Precautions section.
  2.  
  3. Remove or disconnect the following:

    Front wheel
     
    Wheel bearing/axle shaft locknut while depressing the brake pedal
     
    Brake caliper and support it with a piece of wire. It is not necessary to disconnect the brake line from the caliper.
     
    Anti-Lock Brake System (ABS) sensor from the steering knuckle
     

  4.  


NOTE
Do not depress the brake pedal or twist the brake line.



Tie rod end
 
Halfshaft from the knuckle by slightly tapping with a soft hammer. Position the axle shaft nut on the threads of the shaft to protect them when lightly tapping.
 
Lower ball joint nut and separate
 
2 strut-to-knuckle retaining bolts and separate
 
Steering knuckle from the vehicle
 

  1. Place the assembly in a vise. Drive the hub with the inner race from the knuckle with a suitable tool. Remove the inner and outer grease seals.
