  2. Mount the rear axle hub in a soft jaw vise.
    NOTE: Replace the axle hub assembly if it is dropped or a strong shock is given to it.
  3. Using SST and 2 bolts (Diameter: 12 mm, Pitch: 1.5 mm), remove the speed sensor.
  SST 09520-00031 (09520-00040, 09521-00020), 09950-00020
  NOTE:
  - If the sensor rotor is damaged, replace the axle hub assembly.
  - Do not scratch the contacting surface of axle hub and speed sensor.
5. Install a new front speed sensor.
  1. Clean the contacting surface of the axle hub and a new speed sensor.
    NOTE: Take care not to stick any foreign objects to the sensor rotor.
