Axle Support Bearing

The procedure to service the wheel bearing with ABS necessitates you to start by extracting the ABS speed sensor through 2 pins using a pin punch and hammer together with Special Service Tool: 09520-00031 (09520-00040, 09521-00020). Install the axle hub assembly inside a soft jaw vise but replace it immediately after strong shock impacts. Proceed with the removal of the ABS speed sensor by following protocol presented by Special Service Tool: 09520-00031 (09520-00040, 09521-00020), 09950-00020, and 2 bolts (Diameter: 12 mm, Pitch: 1.5 mm) while being mindful of contamination prevention on the sensor rotor and ensuring a direct straight pullout to avoid breaking it. Replacement of the axle hub assembly is necessary if the sensor rotor shows damage and you should not let the contacting surfaces of the axle hub and speed sensor come into contact with any foreign matter. After cleaning the contacting surface of both components apply the new ABS speed sensor onto the axle hub which should be positioned with its connector facing downward. When using Special Service Tool: 09210-76011 to install the new ABS speed sensor it is important to avoid directly tapping the speed sensor with a hammer while performing inspections for foreign matter on the detection portion and applying press force slowly in a straight direction.

Begin disassembly by removing the ABS speed sensor.

Install the front axle hub with Special Service Tool: 09608-32010, 09950-60010 (09951-00550), 09950-70010 (09951-07150) and a press.

Place the dust cover and secure it with the 3 bolts using a torx socket (T30), ensuring a torque of 8.3 Nm (85 kgf-cm, 74 inch lbs.).

Use a dial indicator; the maximum backlash should not exceed 0.05 mm (0.0020 inch), and the maximum deviation at the surface of the axle hub outside the hub bolt should not exceed 0.07 mm (0.0028 inch).

Use snap ring pliers to take off the snap ring, place the inner race on the outside of the bearing, and employ Special Service Tool: 09310-35010, 09527-17011 with a press to remove the bearing.

Do not tap the speed sensor directly with a hammer, ensure no foreign matter is present on the detection portion, and press the ABS speed sensor in straight and slowly.

The maximum allowable backlash is 0.05 mm (0.0020 inch); if exceeded, replace the bearing.

Disconnect the ABS speed sensor connector, then remove the front axle hub by taking out the 4 bolts with a torque of 56 Nm (571 kgf-cm, 41 ft. lbs.).

Reattach the dust cover with the 3 bolts, ensuring a torque of 8.3 Nm (85 kgf-cm, 74 inch lbs.).

Installation follows the reverse order of removal.

Begin by removing the front wheel, ensuring a torque of 103 Nm (1,050 kgf-cm, 76 ft. lbs.).
