Illustration 9 g00907688
Differential and Bevel Gear (Rear Axle) (1) Bevel gear (2) Bolt (3) Cup (bearing) (4) Cone (bearing) (5) Nut (6) Bolt (7) Retainer (8) Case (9) Nut (10) Cone (bearing) (11) Cup (bearing)
Install bevel gear (1) onto the assembled case (8) . Apply 4C-9506 Retaining Compound to the threads of bolts (2) . Secure the bevel gear to the case with bolts (2) . Tighten the bolts to a torque wrench setting of 105 5 N m (77 4 lb ft). Install cones (4) and (10) and check for full seating of the bearing cones. Lubricate the cones with axle oil.
Support the assembly in a fixture. Position the assembly so that the pinion gear is pointing vertically downward. Install cups (3) and (11) . Lower the differential assembly into position.

Differential Assembly (12) Cap (13) Bolt
Install caps (12) . Strike each cap with a soft mallet in order to seat the cap. Install bolts (13) and tighten to a torque wrench setting of 220 N m (162 lb ft).
Install nuts (5) and (9) . Use tooling (B) to tighten each nut until slight resistance is felt. Strike both sides of the assembly with a soft mallet in order to seat the bearings. Repeat the process until the rolling resistance increases.

Check the rolling resistance of the differential.
Reposition the carrier in the supporting fixture so that the pinion gear is horizontal. Use tooling (C) to measure the rolling resistance. The rolling resistance must be between 5.2 N m (46 lb in) and 5.9 N m (52 lb in). Adjust one of the nuts (5) or (9) in order to establish the correct rolling resistance. Tighten the nut in order to increase the rolling resistance. Back off the nut in order to reduce the rolling resistance. The rolling resistance must be between 5.2 N m (46 lb in) and 5.9 N m (52 lb in).

Measuring Pinion Backlash
Install tooling (A) . Position the contact point (plunger) at 90 degrees to one of the bevel gear teeth. Adjust the dial indicator so that the contact point (plunger) is just in contact with the tooth. Zero the dial indicator. Hold the pinion gear stationary and rotate the bevel gear back and forth in order to measure the backlash. The bevel gear backlash is the total deflection of the dial indicator. Use tooling (B) to tighten nuts (5) and (9) by equal amounts until the measured backlash is between 0.18 mm (0.007 inch) and 0.32 mm (0.013 inch).
If the measurement is not within the specification, adjust nuts (5) and (9) . Back off nut (5) and tighten nut (9) by the same amount in order to increase the backlash. Back off nut (9) and tighten nut (5) by the same amount in order to decrease the backlash. Adjusting the nuts by the same amount will maintain the correct rolling resistance.
When the backlash and the rolling resistance are within the specification, install retainers (7) and bolts (6) in order
