1.
If the hypoid gear set, carrier, differential case or side bearing has been replaced with new part, adjust the side bearing preload with adjusting
washer. The required thicknesses of the left and right washers can be obtained from the following formulas: T1 = (A - C + D - H') 0.01 + 2.05; T2
= (B - D + H') 0.01 + 1.95; where T1 = required thickness of left side washer in millimeters,
Fig. 24, T2 = required thickness of right side washer
in millimeters,
Fig. 24, A & B = figure marked on the gear carrier, Fig. 25, C & D = figure marked on the differential case, Fig. 26, E & F =
differences in width of left or right side bearing against the standard width (21.00 mm) and figures for A, B, C and D are dimensional variations in
a unit of 1/100 mm against each standard measurement. The decrease or increase in thickness of washers causes change in ring gear-to-pinion
backlash. Before calculation, determine ``G'' value by measuring spacer thickness. If spacer is deformed or scratched, replace.
If values signifying
A, B, C and D are not given, regard value as zero and compute.
2.
Install differential case assembly with side bearing outer races into carrier.
3.
Insert left and right side bearing preload adjusting washers in place between side bearings and housing.
4.
Drive in side bearing spacer between right hand washer and housing.
5.
Align mark on bearing cap with that on carrier and install bearing cap on carrier. Torque bolts to 65-72 ft. lbs.
Fig. 27 Measuring ring & pinion backlash
6.
Measure ring gear-to-drive pinion backlash with a dial indicator and adjust to .0051-.0071 inch,
Fig. 27. If below the specified value, replace left
washer with a thinner one and right washer with a thicker one. If over, replace left washer with a thicker one and right washer with a thinner one.
To maintain correct preload at all times, do not change total thickness of washers.
