REAR DRIVE SHAFT REMOVAL/INSTALLATION

id031300145000

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.  Remove the locknut with the brake pedal depressed. (See Locknut Installation Note.)

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.

8.  Install a spare nut onto the drive shaft.

9.  Tap the nut with a copper hammer and separate the drive shaft from the axle.

Rear Drive Shaft Removal Note

Caution

•  The oil seal could be damaged by the end of the 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 specification.

•  If it exceeds the specification, 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.  Insert the rear drive shaft to the wheel hub component.

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

4.  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 locknut to 100—150 N·m {11—15 kgf·m, 74—110 ft·lbf} torque.

(2)  Loosen locknut to 180°

(3)  Tighten locknut to 236—274 N·m {25—27 kgf·m, 175—202 ft·lbf} torque.
