The wheel speed sensor requires first removing both the rear wheel then the rear brake drum sub-assembly from TMMC Made and TMC Made drum types. The second step involves disconnecting the skid control sensor wire by removing its connector from the sensor unit. The rear axle hub bearing assembly needs removal from the LH side afterwards. A soft jaw vise should be used to mount the rear axle hub while the hub assembly needs replacement after any dropping incident or strong shock. Use a hammer for pin punch operations to drive out the 2 pins which will separate both attachments from Special Service Tool: 09520-00031. To dismount the skid control sensor from the rear axle hub you need Special Service Tool: 09520-00031, 09520-00040 along with two bolts (12 mm Diameter, 1.5 mm pitch). Replacing the axle hub assembly becomes necessary after any detected sensor rotor damage and you should prevent contact damage on the speed sensor because of its direct surface relationship with the hub.
