HINT:

Replace the RH side by using the same procedures as those for the LH side.

1. REMOVE REAR WHEEL 
2. DISCONNECT SKID CONTROL SENSOR WIRE 
   1. Disconnect the connector from the skid control sensor.
3. SEPARATE REAR DISC BRAKE CALIPER ASSY LH (See  OVERHAUL  ) 
4. REMOVE REAR DISC (See  OVERHAUL  ) 
   1. Place matchmarks on the rear disc and the axle hub.
   2. Remove the rear disc.
5. REMOVE REAR AXLE HUB & BEARING ASSY LH (See  REPLACEMENT  ) 
6. REMOVE SKID CONTROL SENSOR 
   1. Mount the hub & bearing assy on a soft jaw vise.
      NOTE: Replace the hub & bearing assy if it is dropped or receives a strong shock.
   2. Using a pin punch and hammer, drive out the 2 pins and remove the 2 attachments from SST(s).
   3. Using SST(s) and 2 bolts (Diameter: 12 mm, pitch: 1.5 mm), remove the skid control sensor from the hub & bearing assy.

      NOTE:

      • If the sensor rotor is damaged, replace the hub & bearing assy.
      • Do not scratch the contacting surface of the hub & bearing assy and the skid control sensor.
7. INSTALL SKID CONTROL SENSOR 
   1. Clean the contacting surface of the rear axle hub and a assy and a new skid control sensor.
      NOTE: Make sure the sensor rotor is clean.
   2. Place the skid control sensor on the rear axle hub so that the connector makes the lowest position under the on vehicle condition.
