6. Install the drive pinion assembly and companion flange with the mating marks
properly aligned. Tighten the companion flange self-locking nut to the
specified torque while holding the companion flange with special tool
MB990850.
Tightening torque: 186 +/- 29 N.m (137 +/- 21 ft-lb)

7. Use special tools MB990685 and MB990326 to measure the drive pinion
turning torque (with drive pinion oil seal) to verify that the drive pinion turning
torque complies with the standard value.
Standard value:

8. If the turning torque is not within the standard value, check the tightening
torque of the companion flange self-locking nut, and the installation of the oil
seal.
>>F<< DIFFERENTIAL GEAR BACKLASH ADJUSTMENT Adjust the differential gear backlash by the following procedure:
1. Assemble the side gears, side gear spacers, pinion gears, and pinion washers
into the differential case.

2. Temporarily install the pinion shaft.
3. Insert a wedge between the side gear and the pinion shaft to lock the side gear.
4. While locking the side gear with the wedge, measure the differential gear
backlash with a dial indicator on the pinion gear.
Measure by the same procedure for the other pinion gear.
Standard value: 0.01 - 0.250 mm (0.0004 - 0.0098 inch)
Limit: 0.2 mm (0.01 inch)

5. If the backlash exceeds the limit value, adjust it by replacing the side gear
spacers.
6. If adjustment is not possible, replace the side gears and pinion gears as a set.
7. Check that the backlash is within the limit value and that the differential gear
turns smoothly. >>G<< LOCK PIN INSTALLATION 1. Align the pinion shaft lock pin hole with the differential case lock pin hole, and
drive in the lock pin.
2. Stake the lock pin with a punch on both sides.

>>H<< DRIVE GEAR INSTALLATION 1. Clean the drive gear attaching bolts.
2. Remove the adhesive adhered to the threaded holes of the drive gear by turning
the tap (M 10 X 1.25). Clean the threaded holes by applying compressed air.
