8. Check that the backlash is within the limit value and that the

differential gear turns smoothly.

.

>>F<< 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.

.

>>G<< 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 (M10 x 1.25). Clean the
threaded holes by applying compressed air.

3. Apply 3M

 AAD Part No. 8730, 8731 or equivalent to the

threaded holes of the drive gear.

4. Install the drive gear onto the differential case with the

mating marks properly aligned. Tighten the bolts to the
specified torque in a diagonal sequence.

Tightening torque: 137

− 167 N⋅m (101 − 123 ft-lb)

>>H<< SIDE BEARING INNER RACE INSTALLATION
Use special tool MD998812, MD998829 to press-fit the side
bearing inner races into the differential case.

.

>>I<< BEARING CAP INSTALLATION
Align the mating marks on the gear carrier and the bearing cap,
and then tighten the bearing cap.

.

>>J<< DRIVE GEAR BACKLASH ADJUSTMENT
Adjust drive gear backlash as follows:
1. Using special tools MB991367 and MB991385, temporarily

tighten the side bearing nut to just before preloading of the
side bearing.

2. Measure the drive gear backlash.

Standard value: 0.13

− 0.18 mm (0.005 − 0.007 inch)

3. Using special tools MB991367, MB991385, adjust the

backlash to standard value by moving the side bearing nut
as shown.
NOTE: First loosen the side bearing nut then tighten the
side bearing nut the same amount as when it was loosened.

4. Using special tools MB991367 and MB991385, apply the

preload, turn down both right and left side bearing nuts on
half the distance between centers of two neighboring holes.

5. Choose and install the lock plate (two kinds).
6. Check the final drive gear tooth contact. If poor contact is

evident, make adjustment. (Refer to GROUP 26, Inspection
Before Disassembly

P.26-41

.)

7. Measure the drive gear runout.

Limit: 0.05 mm (0.002 inch)

8. When drive gear runout exceeds the limit, remove the

differential case and then the drive gears, moving them to
different positions and reinstall them.

9. If adjustment is not possible, replace the differential case or

drive gear and drive pinion as a set.
