Rotate the ring gear several times.

Look through the service filler hole or remove the ring gear to check the tooth contact pattern.

NOTICE:

1. Check the tooth contact pattern at 4 or more positions around the circumference of the ring gear.
   
2. When replacing washers (backlash adjustment, preload adjustment or tooth contact adjustment), reapply Prussian blue.
   

HINT:

The Prussian blue pattern indicates the tooth contact points.

If the teeth are not contacting properly, select a driven pinion bearing front (outer race) side washer from the chart and install the washer.

NOTICE:

If a washer (for tooth contact adjustment) is replaced with one that has a different thickness, the backlash will also change. Therefore, it is necessary to adjust the backlash.

Perform the following procedures for face or flank contact:

1. Use the backlash adjustment washer (ring gear mounting case washer) to move and adjust the ring gear. (*1)
   

2. Perform the ring gear and driven pinion tooth contact inspection again.
   

   HINT:

   If the tooth contact is incorrect, repeat step *1.

3. Perform the ring gear and driven pinion backlash inspection. If the ring gear and driven pinion backlash is not within the standard range, replace the ring gear and driven pinion with new ones.
   

Perform the following procedures for heel or toe contact:

1. Select a transfer driven pinion bearing front (outer race) side washer (transfer output shaft washer) from the chart and install the washer.
   

   NOTICE:

   Do not reuse a transfer pinion bearing spacer.
