DISASSEMBLY





1. REMOVE DIFFERENTIAL CASE LH TAPERED ROLLER BEARING
a. Set the differential case in a vise.
b. Using SST, remove the bearing RH from the differential case.
SST 09950-40011 (09951-04010, 09952-04010, 09953-04020, 09954-04010, 09955-04061, 09958-04010)

NOTICE: Apply oil or equivalent to the ends and screw portions of SST.





2. REMOVE DIFFERENTIAL CASE RH TAPERED ROLLER BEARING
a. Set the differential case in a vise.
b. Using SST, remove the bearing LH from the differential case.
SST 09950-40011 (09951-04010, 09952-04010, 09953-04020, 09954-04010, 09955-04061, 09958-04010)
3. REMOVE DIFFERENTIAL CASE





a. Set the differential case in a vise.
b. Tap out the straight pin from the differential case with a 5 mm pin punch.








c. Remove the following parts from the differential case.

INSPECTION
1. INSPECT DIFFERENTIAL CASE TAPERED ROLLER BEARING
a. Check the bearing for abnormal wear or discoloration.

HINT: Replace the bearing with a new one if abnormal wear or discoloration is found.

REASSEMBLY
1. INSTALL DIFFERENTIAL CASE





a. Apply ATF WS to the side gear thrust washer and install it to the side gear.
b. Apply ATF WS to the side gear thrust washer and install it to the pinion.
c. Install the side gear and pinion to the differential case.
d. Install the pinion shaft to the differential case so that the straight pin holes of the pinion shaft and differential case are aligned.





e. Set the pinion side and inspect the side gear backlash.
Standard backlash: 0.05 to 0.20 mm (0.0020 to 0.0079 inch)

HINT:
^ Replace the side gear thrust washers with the same size for both the right and left side gears if the value is outside the specified range.
^ Ensure that rotation is smooth if side gear backlash is within the specified range.

If the backlash exceeds the specified range, replace the side gear thrust washer with thinner one. If the backlash is less then the specified range, replace the side gear thrust washer with thicker one.

Standard Side Gear Thrust Washer Thickness:

f. Using a 5 mm pin punch, tap in the straight pin to the differential case.





g. Using a chisel, caulk the external circumference of the differential case straight pin hole.





2. INSTALL DIFFERENTIAL CASE RH TAPERED ROLLER BEARING
a. Using SST and a press, press in the bearing RH to the differential case.
SST 09710-22021 (09710-01031), 09950-70010 (09951-07100)

HINT: There are 24 bearing rollers in bearing RH.





3. INSTALL DIFFERENTIAL CASE LH TAPERED ROLLER BEARING
a. Using SST and a press, press in the bearing LH to the differential case.
SST 09710-22021 (09710-01031), 09950-70010 (09951-07100)

HINT: There are 22 bearing rollers in bearing LH.
