Make the differential case bearing and side gear shaft plate washer snug by tapping on the ring gear with a plastic hammer.

Set the dial indicator perpendicular to the end of the ring gear face.

While holding the rear drive pinion companion flange rear, rotate the ring gear and measure the backlash.

Backlash:
0.13 to 0.18 mm (0.0051 to 0.0071 in.)

If the backlash is not within the specified range, select a side gear shaft plate washer that will set the ring gear backlash within the specified range and install it into the ring gear back side.

Select a thicker side gear shaft plate washer so that the clearance between the case bearing outer race end on the ring gear teeth side and the carrier becomes zero or close to zero.

Make the differential case bearing and side gear shaft plate washer snug by tapping on the ring gear with a plastic hammer.

Set the dial indicator perpendicular to the end of the ring gear face.

While holding the rear drive pinion companion flange, rotate the ring gear and measure the backlash.

Backlash:
0.13 to 0.18 mm (0.0051 to 0.0071 in.)

If the backlash is not within the specified range, adjust the thickness of the right and left side gear shaft plate washers by an equal amount so that the backlash comes within the specified range.

29. INSPECT RUNOUT OF REAR DRIVE PINION COMPANION FLANGE

Using a dial indicator, measure the runout of the companion flange vertically and horizontally.

Maximum runout:
0.09 mm (0.0035 in.)

If the runout is greater than the maximum value, replace the rear drive pinion companion flange sub-assembly.

30. INSTALL REAR DRIVE PINION NUT

Using a SST and a hammer, stake the drive pinion nut.

31. INSTALL REAR DIFFERENTIAL SIDE GEAR SHAFT OIL SEAL

Using SST and a hammer, install 2 new oil seals.

SST
09213-70011
09950-60010(09951-00410,09951-00620,09952-06010)
09950-70010(09951-07100)

Oil seal installation depth:
-0.5 to 0.5 mm (-0.020 to 0.020 in.)

Apply MP grease to the oil seal lip.

32. INSTALL REAR DIFFERENTIAL DRAIN PLUG

Using a hexagon wrench (10 mm), install the differential drain plug with a new gasket.

Torque:
49 N*m{ 500 kgf*cm, 36 ft.*lbf}

33. REMOVE REAR DIFFERENTIAL CARRIER

Remove the differential carrier from the overhaul stand, etc.

34. INSTALL REAR DIFFERENTIAL BREATHER PLUG OIL DEFLECTOR

Install the oil deflector and bolt to the carrier cover.

Torque:
8.0 N*m{ 82 kgf*cm, 71 in.*lbf}

35. INSTALL REAR DIFFERENTIAL CARRIER COVER

Clean any residual FIPG material on the contact surfaces using gasoline or alcohol.

Apply FIPG to the carrier cover.

FIPG:
08826-00090, THREE BOND 1281 or equivalent

HINT:

Apply FIPG in a continuous bead, approximately 2 to 3 mm (0.08 to 0.12 in.) in diameter on the entire sealing surface.

Overlap FIPG at least 10 mm (0.39 in.) or more at the beginning and the end of application.

Install the carrier cover within 3 minutes after applying FIPG.

Do not fill the differential with oil or drive the vehicle immediately after installing the differential carrier cover. Allow at least one hour for the sealant to dry before filling the differential. Avoid sudden acceleration and deceleration for at least 12 hours after installation of parts using FIPG sealant.

Install the carrier cover with the 8 bolts.

Torque:
47 N*m{ 480 kgf*cm, 35 ft.*lbf}

36. INSTALL REAR DIFFERENTIAL BREATHER PLUG

Install the breather plug to the carrier cover.

Torque:
21 N*m{ 210 kgf*cm, 15 ft.*lbf}
