Caution
•  Performing the following procedures could cause an open circuit in the rear ABS wheel-speed sensor wiring harness if it is pulled by mistake. Before servicing, disconnect the rear ABS wheel-speed sensor and set it aside so that the wiring harness will not be pulled by mistake.
•  Do not allow a magnetized tool such as a magnetized screwdriver to come into contact with the ABS sensor rotor. If the ABS sensor rotor becomes magnetized, it will be unable to read the ABS wheel-speed sensor waveform correctly resulting in an ABS system malfunction to be determined and the inability to perform ABS control. If a magnetized object comes into contact with the ABS sensor rotor, it will be necessary to newly replace the rear drive shaft (ABS sensor rotor).

1.  Switch the ignition ON (engine off).

2.  Release the electric parking brake.

3.  Switch the ignition off.

4.  Disconnect the negative battery terminal. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

5.  Remove the wheel and tire. (See WHEEL AND TIRE REMOVAL/INSTALLATION.)

6.  Drain the differential oil. (See DIFFERENTIAL OIL REPLACEMENT.)

7.  Disconnect the rear ABS wheel-speed sensor wiring harness and the electric parking brake motor gear unit connector, and set them aside so that they do not interfere with the servicing. (See REAR ABS WHEEL-SPEED SENSOR REMOVAL/INSTALLATION [4WD].)

Caution
•  When removing the locknut, remove it manually without using an electric or pneumatic tool. Otherwise, the locknut may seize.
•  When removing the locknut, do not apply load at the ground to the axle. Otherwise, it could damage the wheel hub.

9.  Remove the rear brake caliper component installation bolts.

12.  Remove the wheel hub component. (See WHEEL HUB COMPONENT REMOVAL/INSTALLATION [4WD].)

13.  Remove the dust cover. (See WHEEL HUB COMPONENT REMOVAL/INSTALLATION [4WD].)

14.  Disconnect the rear trailing link from the hub support. (See REAR TRAILING LINK REMOVAL/INSTALLATION.)

15.  Remove the rear coil spring. (See REAR COIL SPRING REMOVAL/INSTALLATION.)

16.  Disconnect the rear shock absorber from the hub support. (See REAR SHOCK ABSORBER REMOVAL/INSTALLATION.)

17.  Disconnect the rear lateral link from the hub support. (See REAR LATERAL LINK REMOVAL/INSTALLATION.)

18.  Disconnect the rear upper arm from the hub support. (See REAR UPPER ARM REMOVAL/INSTALLATION [4WD].)

19.  Remove the hub support. (See WHEEL HUB COMPONENT REMOVAL/INSTALLATION [4WD].)

20.  Remove in the order shown in the figure.

21.  Install in the reverse order of removal.

22.  Add rear differential oil. (See DIFFERENTIAL OIL REPLACEMENT.)

Rear Drive Shaft Removal Note

Caution
•  The oil seal could be damaged by the end of the rear drive shaft. When removing the rear drive shaft, be careful not to damage the oil seal. If the oil seal is damaged, replace it with a new one.
•  Be careful not to damage the rear drive shaft boot.
•  Be careful not to damage the rear ABS sensor rotor.

1.  Insert a tire lever or equivalent tool between the rear differential-side outer ring and the rear differential.

2.  Move the tire lever or the equivalent in the direction of the arrow shown in the figure and detach the rear differential and the rear drive shaft.

3.  Remove the rear drive shaft by pulling it to the wheel side until it is removed from the differential.


Rear Drive Shaft Clip Installation Note

1.  Install a new clip to the clip groove at the end of the rear drive shaft with the clip opening facing upward.

2.  Verify that the outer diameter of the clip is within the standard.

Standard
Less than 25.2 mm {0.992 in}
•  If it exceeds the standard, repeat installation using a new clip.


Rear Drive Shaft Installation Note

Caution
•  The oil seal could be damaged by the end of the rear drive shaft. When installing the rear drive shaft to the rear differential, be careful not to damage the oil seal. If the oil seal is damaged, replace it with a new one.

1.  Apply rear differential oil to the oil seal lip.

2.  Install the rear drive shaft to the rear differential.

3.  After installation, verify that the rear drive shaft is securely held by the clip by pulling the outer ring on the rear differential side towards the axle side.


Locknut Installation Note

Caution
•  When installing the locknut, install it manually without using an electric or pneumatic tool. Otherwise, the locknut may seize and the tightening force of the wheel hub may decrease and cause excessive play or abnormal noise.
•  When installing the locknut, do not apply load at the ground to the axle. Otherwise, it could damage the wheel hub.

1.  If dust or grease is on the drive shaft thread area, wipe it off with a cloth.

2.  Tighten the locknut using the following procedure and with the brake pedal depressed.

(1)  Tighten to 100—150 N·m {11—15 kgf·m, 74—110 ft·lbf}.
(2)  Loosen to 180°.
(3)  Tighten to 236—274 N·m {25—27 kgf·m, 175—202 ft·lbf}.
