TOTAL PRELOAD INSPECTION
1. Turn companion flange in both directions 20 times or more to set
bearing rollers, then check total preload with special service tool.

If the preload value is out of standard, adjust by changing side
bearing adjusting shim thickness (side retainer side).
–If preload value too large, increase the side bearing adjusting
shim thickness.
–If preload value too small, decrease the side bearing adjusting shim thickness.

CAUTION:

Tighten the drive pinion nut by very small degrees until the specified preload in achieved. Do
not tighten nut more than necessary.

First select the thicker washer, then gradually select thinner one.

Do not apply preload more than necessary.
Reassembly of drive pinion assembly

ion.
2. Remove the companion flange using puller.
3. Drive out the drive pinion from carrier case using copper hammer.
4. Apply gear oil to bearing portion.
5. Install the drive pinion with selected drive pinion adjusting washer and drive pinion bearing adjusting
washer into the carrier case, then install bearing.
6. Apply multi-purpose grease to oil seal lips.
7. Drive oil seal into the final drive using drift.
8. Install companion flange.
9. Apply oil to new drive pinion lock nut threads and seating sur-
face, then install it onto the drive pinion.
CAUTION:
Do not reuse drive pinion lock nut. Always replace nut with
new one.
10. Turn the companion flange more than 20 times to seat bearing.
11. Tighten the drive pinion lock nut to specified torque.
CAUTION:
Do not overtighten the nut.
12. Measure the preload using preload gauge.Drive pinion lock nut torque : 186.2 N·m (19 kg-m, 137 ft-lb)
Pinion bearing preload without oil seal : 0.78 - 1.57 N·m (0.08 - 0.16 kg-m, 7 - 13 in-lb)
When the washer thickness is increased : Preload will decrease.
When the washer thickness is decreased : Preload will increase.
