ASSEMBLY SERVICE POINTS
>>A<< TAPERED ROLLER BEARING INSTALLATION

Using special tool MB990937, press install the taper roller bearing.

>>B<< TAPERED ROLLER BEARING INSTALLATION

>>C<< SPACER, SIDE GEAR, WASHER, PINION AND PINION SHAFT, PINION SHAFT HOLDER, LOCK PIN, FRONT OUTPUT SHAFT, SNAP RING, CENTER DIFFERENTIAL FLANGE, INSTALLATION

1. Mount a spacer on the back surface of the side gear, and then install the side gear in the differential case.

NOTE: When a new side gear is to be installed, use a medium thickness spacer [0.93 to 1.00 mm (0.0366 to 0.0395 inch)].

2. Place the washers on the back of the pinions, and simultaneously mesh the four pieces with the side gears. Place them into position while rotating them. Then, install the pinion shaft holder.
3. Insert the pinion shaft.

4. Install the lock pin so that it will be oriented in the direction shown.
5. Install the front output shaft on the side gear, and install the snap ring.
6. Mount a spacer on the back surface of the side gear, and then install the side gear in the differential case.

NOTE: When a new side gear is to be installed, use a medium thickness spacer [0.93 to 1.00 mm (0.0366 to 0.0395 inch)].

7. Install the center differential flange by aligning the matching marks, and temporarily tighten the four machine screws.

8. Measure the backlash between the side gear and pinion.
Standard value: 0.025 - 0.150 mm (0.0010 - 0.0059 inch)
9. If the backlash is out of the standard value, select a spacer and re-measure the backlash.

NOTE: Adjust until the backlash on both sides are equal.

>>D<< DIFFERENTIAL DRIVE GEAR INSTALLATION

1. Apply sealant (3M STUD Locking No.4170 or equivalent) to the entire threaded portion of the bolt.

2. Tighten to the specified torque in the illustrated sequence.
Tightening torque: 133 ± 4 Nm (98 ± 3 ft. lbs.)
