Differential Case

NOTE: Apply differential gear oil to each sliding part.

Install the differential bevel gear and differential bevel pinion together with the thrust washer, and install the pinion shaft.

Measure the backlash between the differential bevel gear and differential bevel pinion, and select a thrust washer.

Measure the backlash between the differential bevel gear and differential bevel pinion using the magnet stand and dial gauge (lever type).

NOTE:

Set the dial gauge (lever type) so that its needle contacts the differential bevel gear tooth.
When measuring, fix the differential bevel pinion in place.
