Repair Procedures

Removal

Be careful not to damage parts located under the vehicle (floor under cover, fuel filter, fuel tank, and canister) when lifting the vehicle with a lift. (Refer to General Information - Jack Lifting Points and Support Points)

1. 1
   Turn the ignition switch OFF, then disconnect the negative (-) battery cable.
2. 2
   Loosen the wheel nuts slightly. Raise the vehicle and make sure it is securely supported.
3. 3
   Remove the rear wheel and tire (A) from the rear hub.

   Tightening torque: 107.9–128 N·m

   Be careful not to damage the hub bolts when removing the rear wheel and tire (A).

   

4. 4
   Remove the rear brake caliper. (Refer to Brake System - "Rear Disc Brake")
5. 5
   Remove the rear brake disc (A).

   

6. 6
   Disconnect the rear wheel speed sensor connector (A).

   

7. 7
   Remove the hub assembly and dust cover (A) after loosening the mounting bolts.

   Tightening torque: 98.1 - 118 N·m

   

8. 8
   Turn the ignition switch OFF, then disconnect the negative (-) battery cable.
9. 9
   Loosen the wheel nuts slightly. Raise the vehicle and make sure it is securely supported.
10. 10
    Remove the rear wheel and tire (A) from the rear hub.

    Tightening torque: 107.9–128 N·m

    Be careful not to damage the hub bolts when removing the rear wheel and tire (A).

    

11. 11
    Remove the rear wheel guard. (Refer to Body - "Rear Wheel Guard")
12. 12
    Disconnect the rear wheel speed sensor connector (A).

    

13. 13
    Remove the mounting bolt of the rear wheel speed sensor cable bracket (A).

    Tightening torque: 19.6–29 N·m

    

14. 14
    Disconnect the EPB actuator connector (A).

    

15. 15
    Remove the rear wheel speed sensor (A) after loosening the mounting bolt.

    Tightening torque: 6.9–10.8 N·m

    

Replacement

1. 1
   Remove the rear wheel hub bearing assembly. (Refer to Drive Shaft and Axle - "Rear Hub - Carrier")
2. 2
   Secure the rear wheel hub bearing assembly (A) in a vise.

   When clamping in a vise, use a cloth to avoid damaging the hub bearing assembly. Be careful, as excessive clamping force in the vise may damage the hub bearing assembly.

   

3. 3
   Check the direction of the sensor cover (A).

   

4. 4
   Remove the sensor cover by tapping the gap between the sensor cover and the hub bearing assembly with a scraper (A).

   

   To gradually widen the gap, tap around the bearing cover 10-20 times. When removing the sensor cover, pull it straight out to avoid damaging the tone wheel or encoder.

5. 5
   Check the tone wheel or encoder (A) for distortion or damage.

   

   After removing the sensor cover, check the tone wheel or encoder for damage, and replace the hub bearing if it is deformed. If the tone wheel is deformed, it may cause the MIL to illuminate or other problems.

6. 6
   Position the sensor cover in the same direction as the sensor cover connector (A) was positioned before removal.

   

   Before installing the sensor cover, do not allow foreign material and contaminants to enter the hub bearing assembly (A).

7. 7
   Install the sensor cover (A) using the special service tool (09527-AL500).

   

   Tap with a hammer until there is no gap between the SST and the hub bearing assembly, then install the sensor cover. Be careful not to install the sensor cover at an angle, as this may damage the tone wheel or encoder. When installing the sensor cover, tap it until the gap between the sensor cover and the hub bearing assembly disappears.

8. 8
   Install the rear wheel hub bearing assembly. (Refer to Drive Shaft and Axle - "Rear Hub - Carrier")

Installation

1. To install, reverse the removal procedure.

Inspection

1. 1
   Measure the output voltage between the wheel speed sensor terminal and body ground.

   To protect the wheel speed sensor, use a 100 Ω resistor when measuring the output voltage, as shown in the illustration.

   

2. 2
   Compare the change in the wheel speed sensor output voltage with the normal output voltage change, as shown below.

   

   V_low: 0.59–0.84 V V_high: 1.18–1.68 V Frequency range: 1–2,000 Hz
