To install:

  1. Using SST 09950-60020 and 09387-00041 and a press, insert a new hub bearing, with its magnetic rotor side facing the inside of the vehicle, until it reaches the end of the steering knuckle.
    NOTE
    Note the following:



    Do not remove the inner race because the hub bearing is built into the oil seal.
     
    Do not use bearings that have been removed.
     
    Do not wipe off any grease that has been applied to new bearings.
     
    Do not bring magnets close to the magnetic rotor surface of the bearing.
     
    Keep the magnetic rotor surface of the bearing free of foreign matter.
