degreased sufficiently.
9.
Install drive gear on the mounting bolts, and then tighten to the
specified torque. Refer to "COMPONENTS".
CAUTION:
• Tighten bolts in a crisscross fashion.
• After tightening the bolts to the specified torque, tighten
the bolts additionally by turning the bolts 31 to 36
degrees.
10. Press side bearing inner races to differential case, using the drift
and the base.
CAUTION:
Never reuse side bearing inner race.
11. Install differential case assembly with side bearing outer races
into gear carrier.
12. Measure side bearing preload. If necessary, select the appropri-

drive pinion backlash, and total preload torque. Refer to "Drive
Gear Runout", "Tooth Contact", "Backlash", "Total Preload Torque".
Recheck above items. Readjust the above description, if necessary.
18. Apply sealant to mating surface of rear cover.
• Use Genuine Silicone RTV or equivalent. Refer to
CAUTION:
Remove old sealant adhering to mounting surfaces. Also
