INSTALL DIFFERENTIAL SIDE GEAR
| *1 | Differential Side Gear |
| *2 | Conical Spring Washer |
| *3 | No. 1 Front Differential Side Gear Thrust Washer |
|
Toyota Genuine ATF WS |
Coat the 2 differential side gears, 2 No. 1 front differential side gear thrust washers and 2 conical spring washers with ATF.
| *1 | Differential Side Gear |
| *2 | Conical Spring Washer |
| *3 | No. 1 Front Differential Side Gear Thrust Washer |
Install the 2 differential side gears, 2 No. 1 front differential side gear thrust washers and 2 conical spring washers to the differential case.
Set SST as shown in the illustration and tighten it.
| *a | Turn | *b | Hold |
Note
Do not overtighten SST, as doing so will damage the differential side gears, conical spring washers, No.1 front differential side gear thrust washers and differential case.
Tech Tips
Tighten SST to create the necessary clearance to install the front differential pinions.
When installing the front differential pinions, do not overtighten SST, as it is necessary to rotate the differential side gears.
Coat the 2 front differential pinions and 2 front differential pinion thrust washers with ATF.
|
Toyota Genuine ATF WS |
| *a | Turn |
Using SST as shown in the illustration, rotate the differential side gear and install the 2 front differential pinions and 2 front differential pinion thrust washers.
CAUTION:
Be careful not to catch your fingers between the front differential pinions and differential case.
Note
Do not drop the front differential pinions and front differential pinion thrust washers.
INSPECT DIFFERENTIAL SIDE GEAR BACKLASH
Set SST as shown in the illustration and tighten it.
| *a | Turn | *b | Hold |
Hold the differential case in a vise between aluminum plates.
Note
Do not overtighten the vise.
| *1 | No. 1 Front Differential Pinion Shaft |
Install the No. 1 front differential pinion shaft to the front differential pinion as shown in the illustration.
Using SST and a dial indicator, measure the front differential pinion backlash.
| Standard Backlash |
|---|
| 0.05 to 0.15 mm (0.00197 to 0.00590 in.) |
If the backlash is not as specified, replace the No. 1 front differential side gear thrust washers with washers of a different thickness. Use the table below to select a No. 1 front differential side gear thrust washer which will ensure that the backlash is within the specification.
| No. 1 Front Differential Side Gear Thrust Washer Thickness | ||||||||||||
|---|---|---|---|---|---|---|---|---|---|---|---|---|
|
Tech Tips
Select front No. 1 differential side gear thrust washers of the same thickness for both the right and left side.
INSTALL FRONT NO. 1 DIFFERENTIAL PINION SHAFT
Coat a No. 1 front differential pinion shaft with ATF.
|
Toyota Genuine ATF WS |
Install the No. 1 front differential pinion shaft to the differential case so that the hole for the front differential pinion shaft straight pin is aligned with the hole in the differential case.
INSPECT DIFFERENTIAL SIDE GEAR THRUST AMOUNT
| *a | Thrust Amount |
Using SST and a dial indicator, measure the thrust amount of the differential side gear.
| Standard Thrust Amount |
|---|
| 0.08 mm (0.00314 in.) or less |
Tech Tips
Measure the differential side gear thrust amount while slowly rotating the differential side gear.
Make sure to measure the differential side gear thrust amount for both of the differential side gears.
If the result is not as specified, replace the 2 conical spring washers, 2 differential side gears and 2 front differential pinions.
INSPECT DIFFERENTIAL CASE
Using SST, rotate the differential side gear as shown in the illustration.
| Standard |
|---|
| The front differential side gear does not lock when rotated in either direction. |
If the differential side gear locks, perform all remaining inspection procedures.
Replace any parts that do not meet the specifications.
If the differential side gear locks after performing the inspection procedures, replace the differential case.
INSTALL FRONT DIFFERENTIAL PINION SHAFT STRAIGHT PIN
Using a 5 mm pin punch and hammer, install the front differential pinion shaft straight pin.
Note
Align the holes in the differential case and No. 1 front differential pinion shaft and install the front differential pinion shaft straight pin.
Using a chisel and hammer, stake the differential case.
INSTALL FRONT DIFFERENTIAL CASE REAR TAPERED ROLLER BEARING
Using SST and a press, install a new front differential case rear tapered roller bearing to the differential case.
Note
Do not damage the bearing cage during bearing inner race installation.
INSTALL FRONT DIFFERENTIAL CASE FRONT TAPERED ROLLER BEARING
Using SST and a press, install a new front differential case front tapered roller bearing to the differential case.
Note
Do not damage the bearing cage during bearing inner race installation.
INSTALL FRONT DIFFERENTIAL RING GEAR
Using ATF and a heater, heat the front differential ring gear to 90 to 110°C (194 to 230°F).
Note
Do not heat the ring gear to more than 110°C (230°F).
Clean the contact surface of the front differential case.
| *a | Matchmark |
Align the matchmarks, and install the front differential ring gear to the differential case quickly.
Note
Do not install the bolts while the ring gear is hot.
Install and tighten the 12 bolts.
Note
Tighten the bolts in diametrically opposite pairs.
