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.

onto the circumference of oil seal.

17. Check and adjust drive gear runout, tooth contact, drive gear to

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
