PROCEDURE
INSPECT FRONT DIFFERENTIAL CASE
Using SST, rotate the front differential side gear as shown in the illustration.
| Standard |
|---|
| The front differential side gear does not lock when rotated in either direction. |
If the front differential side gear locks, perform all remaining inspection procedures.
Replace any parts that do not meet the specifications.
If the front differential side gear locks after performing the inspection procedures, replace the front differential case assembly.
INSPECT FRONT DIFFERENTIAL SIDE GEAR THRUST AMOUNT
| *a | Front differential side gear thrust amount |
Using SST and a dial indicator, measure the thrust amount of the front differential side gear.
| Standard thrust amount |
|---|
| 0.08 mm (0.00314 in.) or less |
Tech Tips
Measure the front differential side gear thrust amount while slowly rotating the front differential side gear.
Make sure to measure the thrust amount for both of the 2 front differential side gears.
If the result is not as specified, replace the 2 center differential side gear conical spring washers, 2 front differential side gears, 2 front differential pinions and 2 front differential pinion thrust washers.
INSPECT FRONT DIFFERENTIAL PINION BACKLASH
Set SST as shown in the illustration and tighten it.
| *a | Turn | *b | Hold |
| *1 | Front No. 1 Differential Pinion Shaft |
Install the front No. 1 differential pinion shaft to the front differential pinion as shown in the illustration.
Using a dial indicator, measure the front differential pinion backlash.
| Standard backlash |
|---|
| 0.05 to 0.20 mm (0.00197 to 0.00787 in.) |
If the backlash is not as specified, replace the front No. 1 differential side gear thrust washers with washers of a different thickness. Use the table below to select a front No. 1 differential side gear thrust washer which will ensure that the backlash is within the specification.
| 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.
INSPECT FRONT DIFFERENTIAL PINION THRUST WASHER
Using a micrometer, measure the thickness of the front differential pinion thrust washer.
| Minimum thickness |
|---|
| 0.9 mm (0.0354 in.) |
If the thickness is less than the minimum, replace the front differential pinion thrust washer.
INSPECT FRONT NO. 1 DIFFERENTIAL PINION SHAFT
Using a micrometer, measure the outer diameter of the front No. 1 differential pinion shaft.
| Minimum outer diameter |
|---|
| 17.975 mm (0.708 in.) |
If the outer diameter is less than the minimum, replace the front No. 1 differential pinion shaft.
