Illustration 7 g06183206Install shim (1) with the chamfer against the gear.
Illustration 8 g06183207
Illustration 9 g06183217Install lip seal (1) to a depth of 13.50 14.00 mm (0.531 0.551 inch) from the surface of differential housing.
Illustration 10 g06183219Note: Check the o-ring seal for wear or for damage. If necessary, replace the O-ring seal.
Illustration 11 g06183224Use Tooling (C) with a dial type torque wrench to set the rolling torque. Tighten the nut to achieve a rolling torque of 1.74 to 2.58 N.m (15.4 to 22.83 lb in). After installation of the nut, use a suitable hammer and a suitable punch to stake the nut.

Illustration 15 g06183323Slightly tighten bolts (2). Do not tighten bolts (2) at this time.
Illustration 16 g06183686Oscillate the pinion shaft and use Tooling (A) to advance spanner nuts (2) until there is slight backlash and no end play on the bearings.Note: Use the following two Steps to set the proper bearing preload.Use a dial type torque wrench and measure the total rotating torque. Use the following formula to calculate the total rotating torque (TRT): P equals the rotating torque that was measured in Illustration 11. TRT = P + 0.53 N m (5 lb in) to P + 0.80 N m (7 lb in)If the total rotating torque (TRT) is less than the specified amount, tighten the spanner nuts. If the total rotating torque (TRT) is greater than the specified amount, loosen the spanner nuts. Always be sure to maintain a slight backlash.
Illustration 17 g06184678Measure the backlash between the pinion and the bevel gear. The proper backlash setting is between 0.180 mm (0.0071 inch) and 0.320 mm (0.0126 inch).
Illustration 18 g06184688If the backlash is not within the specification, retract one spanner nut and advance the opposite spanner nut equally. This procedure will maintain the bearing preload. If the backlash is less than the specified amount, move the bevel gear in Direction (A). If the backlash is greater than the specified amount, move the bevel gear in Direction (B).
