Toyota Yaris: Differential Case / Inspection
INSPECTION
PROCEDURE
1. INSPECT FRONT NO. 1 DIFFERENTIAL CASE SUB-ASSEMBLY
| (a) Using SST, rotate the front differential side gear as shown in the illustration. SST: 09528-52010 09528-05030 Standard: The front differential side gear does not lock when rotated in either direction.
|
|
2. INSPECT FRONT DIFFERENTIAL SIDE GEAR THRUST AMOUNT
(a) Secure the front differential case assembly with ring gear in a vise between aluminum plates.
NOTICE:
Do not overtighten the vise.
| (b) Using SST and a dial indicator, measure the front differential side gear thrust amount. SST: 09528-52010 09528-05030 Front Differential Side Gear Thrust Amount: 0.08 mm (0.00315 in.) or less HINT:
If the result is not as specified, replace the 2 front differential side gears, 2 front differential pinions and 2 conical springs. |
|
3. INSPECT FRONT DIFFERENTIAL PINION BACKLASH
(a) Set SST as shown in the illustration and tighten it.
| *a | Turn | *b | Hold |
SST: 09528-52010
09528-05010
09953-05010
Torque:
10 N·m {102 kgf·cm, 7 ft·lbf}
| (b) Install the front No. 1 differential pinion shaft to the front differential pinion as shown in the illustration. |
|
(c) Using a dial indicator, measure the front differential pinion backlash.
Standard Backlash:
0.15 mm (0.00591 in.) or less
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.
Front No. 1 Differential Side Gear Thrust Washer Thickness:
| Specified Condition |
|---|
| 1.25 mm (0.0492 in.) |
| 1.30 mm (0.0512 in.) |
| 1.35 mm (0.0531 in.) |
| 1.40 mm (0.0551 in.) |
| 1.45 mm (0.0571 in.) |
| 1.50 mm (0.0591 in.) |
| 1.55 mm (0.0610 in.) |
| 1.60 mm (0.0630 in.) |
| 1.65 mm (0.0650 in.) |
| 1.70 mm (0.0669 in.) |
| 1.75 mm (0.0689 in.) |
| 1.80 mm (0.0709 in.) |
| 1.85 mm (0.0728 in.) |
| 1.90 mm (0.0748 in.) |
| 1.95 mm (0.0768 in.) |
HINT:
Select front No. 1 differential side gear thrust washers of the same thickness for both the right and left side.
4. INSPECT FRONT DIFFERENTIAL PINION THRUST WASHER
| (a) Using a micrometer, measure the thickness of the front differential pinion thrust washer. Minimum Thickness: 0.54 mm (0.0213 in.) If the thickness is less than the minimum, replace the front differential pinion thrust washer. |
|
5. INSPECT FRONT NO. 1 DIFFERENTIAL PINION SHAFT
| (a) Using a micrometer, measure the outer diameter of the front No. 1 differential pinion shaft. Minimum Outer Diameter: 20.499 mm (0.807 in.) If the outer diameter is less than the minimum, replace the front No. 1 differential pinion shaft. |
