Toyota Yaris: Differential Case / Inspection

(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.

(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

If the result is not as specified, replace the 2 front differential side gears, 2 front differential pinions and 2 conical springs.

*a

Turn

*b

Hold

(b) Install the front No. 1 differential pinion shaft to the front differential pinion as shown in the illustration.

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.)

(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.

(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.
