    3. Remove the speed sensor from the rear axle hub and bearing assy using the SST and 2 bolts (90101-12007).

      SST 09520-00031 (09520-00040), 09521-00020, 09950-00020

    NOTE:
    • Pull the speed sensor off straight, being careful not to make contact with the skid control sensor rotor. 
    • If the speed sensor rotor is damaged or deformed, replace the rear axle hub and bearing assy. 
    • Do not scratch the area where the speed sensor contacts the rear axle hub and bearing assy. 
    • Do not attach foreign matter to the speed sensor rotor.
