Nissan Terrano r20e. Manual — part 395

12. Place the differential case assembly in its housing.

13. Install side oil seal.
14. Place side retainer adjusting shims and O-ring on side retainer,

and install them in final drive housing.

Tool number:

ST33720000

I

Align arrows stamped on side retainer and final drive housing.

15. Measure ring gear-to-drive pinion backlash with a dial indicator.

Ring gear-to-drive pinion backlash:

0.13 - 0.18 mm (0.0051 - 0.0071 in)

I

If backlash is too small, decrease thickness of right shim and
increase thickness of left shim by the same amount.
If backlash is too great, reverse the above procedure.

Never change the total amount of shims as it will change the
bearing preload.

16. Check total preload with Tool.
When checking preload, turn drive pinion in both directions
several times to set bearing rollers.
The total pinion bearing preload value with the differential case
assembly should be in accordance with the same value measured
without the differential case assembly. (See point 9.)
The relationship between both is:

If preload is too great, remove the same amount of shim from
each side.

I

If preload is too small, add the same amount of shim to each
side.

Never add or remove a different number of shims for each side
as it will change ring gear-to-drive pinion backlash.
17. Recheck ring gear-to-drive pinion backlash because increase

or decrease in thickness of shims will cause change of ring
gear-to-pinion backlash.

18. Check runout of ring gear with a dial indicator.

Runout limit:

0.05 mm (0.0020 in)

I

If backlash varies excessively in different places, the variance
may have resulted from foreign matter caught between the ring
gear and the differential case.

I

If the backlash varies greatly when the runout of the ring gear
is within a specified range, the hypoid gear set or differential
case should be replaced.
