ADJUSTMENT OF DIFFERENTIAL CASE (R200V)
Side gear Thrust Washer Selection
Whenever side gears or pinion mate gears are replaced, select suitable thrust washers as follows:
1. Clean side gears and pinion mate gears using white gasoline.
2. Before assembling gears, apply hypoid gear oil to frictional surfaces.
3. Install the previously removed thrust washer on right side gear. On left side gear, install a suitable thrust washer. Temporarily tighten differential cases using two screws.





4. Position differential assembly so that right side gear is on the upper side. Place feeler gauge of 0.03 mm (0.0012 inch) thickness between right side gear and thrust washer as shown.
^ Do not place feeler gauge at groove side of differential case.

5. Also place a 0.03 mm (0.0012 inch) additional feeler gauge between right side gear and thrust washer so that it is positioned diagonal to (180° apart from) the feeler gauge described previously.
6. Rotate right side gear with a suitable tool attached to splines. If hard to rotate, replace thrust washer on left side gear with a thinner one.
7. Replace both 0.03 mm (0.0012 inch) feeler gauges with 0.15 mm (0.0059 inch) gauges. At this point, make sure right side gear does not rotate. If it rotates, replace thrust washer on left side gear with a thicker one to prevent rotation.
8. As explained in above example, select suitable thrust washers to ensure that:
a. Both side gears rotate. [0.03 mm (0.0012 inch) feeler gauges are used in this case.]
b. Side gear is held stationary. [0.15 mm (0.0059 inch) feeler gauges are used in this case.]

For quiet and reliable final drive operation, the following five adjustments must be made correctly.
1. Side bearing preload
2. Pinion gear height
3. Pinion bearing preload
4. Ring gear to pinion backlash.
5. Ring and pinion gear tooth contact pattern
