Assembling Unit

Apply gear oil to differential side bearing, place differential side bearing outer races on their respective bearings, and install differential case assembly in differential carrier.
Measure distance "a" and "b".
"a" "b" = Right side shim(s) + Left side shim(s)

Select shim(s) for right and left sides and install them between differential carrier and differential bearing outer races.

NOTE: Two 2.0 mm (0.079 in.) shims for the left side and two 3.0 mm (0.118 in.) shims for the right side are installed as standard. Therefore, choose shims which are close to the ones mentioned above. For example, if "a" - "b" is 10.05 mm (0.396 in.), combination pattern is as follows.

Measure bevel gear backlash by using dial gauge. If backlash is out of range, repeat from step 3).
Drive bevel gear backlash

0.10 - 0.20 mm (0.004 - 0.008 in.)
NOTE:
- Before measurement, hit shims lightly for several times by plastic hammer to position shims in correct position.
- Be sure to apply measuring tip of dial gauge at right angles to convex side (drive side) of tooth.
- Measure at least 4 points on drive bevel gear periphery.
- If backlash is out of specification, change shim(s) so that backlash is within specification.

Assemble differential carrier cover and differential carrier temporarily.
NOTE: Tighten 12 mm thread diameter bolts (1) first, then loosen 8 mm thread diameter bolts (2).

Tightening torque

Front differential cover bolt (12 mm) (a): 85 N.m (8.5 kg-m, 61.5 lb-ft)

Front differential cover bolt (8 mm) (b): 23 N.m (2.3 kg-m, 17.0 lb-ft)

Measure preload of pinion with spring balance (1) or torque wrench (2), and then check composite preload of pinion bearing and side bearing.
NOTE:
- Standard preload is shown in graph, which should be read as follows. Example:
  When preload of pinion is 2.6 kg / 5.73 lb, acceptable composite preload of both pinion bearings and differential side bearings should be between 2.8 and 3.2 kg / 6.17 and 7.05 lb.

- Bearing preload can be checked roughly by using flange holder as shown in the figure. In this measurement, holder arm itself will work as balance weight and torque will be replaced with angle. However, flange should be rotated very slowly with hand support so as not to allow over revolution due to inertia.

As final step, check gear tooth contact as follows.
1. After cleaning tooth surface of 10 bevel gears, paint them with gear marking compound evenly by using brush (1) or sponge etc.

5. Bring painted part up and check contact pattern, referring to the following chart. If contact pattern is not normal, readjust or replace as necessary according to instruction in chart.
NOTE: Be careful not to turn bevel gear more than one full revolution, for it will hinder accurate check.
