Front Differential

A: DISASSEMBLY
1) Remove right and left snap rings from differential, and then remove two axle drive shafts.

NOTE: During reassembly, reinstall each axle drive shaft in the same place from which it was removed.





2) Loosen twelve bolts and remove hypoid drive gear.





3) Drive out straight pin from differential assembly toward hypoid driven gear.

B: ASSEMBLY





1) Install bevel gear and bevel pinion together with washers, and insert pinion shaft.

NOTE: Face the chamfered side of washer toward gear.








2) Measure backlash between bevel gear and pinion. If it is not within specifications, install a suitable washer to adjust it.

NOTE: Be sure the pinion gear tooth contacts adjacent gear teeth during measurement.

Standard backlash: 0.13 - 0.18 mm (0.0051 - 0.0071 inch)





3) Align pinion shaft and differential case at their holes, and drive straight pin into holes from the hypoid driven gear side, using ST.

NOTE: Lock straight pin after installing.

4) Install roller bearing (40 x 80 x 19.75) to differential case.

CAUTION: Do not apply pressure in excess of 10 M (1 ton, 1.1 US ton, 1.0 Imp ton).

NOTE: Be careful because roller bearing outer races are used as a set.

5) Install hypoid driven gear to differential case using twelve bolts.
Tightening torque: T: 62±5 Nm (6.3±0.5 kg-m, 45.6±3.6 ft. lbs.)








6) Position drive axle shaft in differential case and hold it with outer snap ring (28). Using a thickness gauge, measure clearance between the shaft and case is within specifications.

NOTE: If it is not within specifications, replace snap ring with a suitable one.

Clearance: 0 - 0.2 mm (0 - 0.008 inch)
