the ring gear and differential case are not misaligned.
NOTICE:
The ring gear set bolts should not be tightened until the
ring gear has cooled sufficiently.
4. INSTALL RING GEAR SET BOLTS

14. MEASURE TOTAL PRELOAD
Using SST and a torque wrench, measure the preload with the
teeth of the drive pinion and ring gear in contact.
SST 09229±55010
Total preload (at starting):
Drive pinion preload plus
0.5 ± 0.8 N´m (5 ± 8 kgf´cm, 4.3 ± 6.9 in.´lbf)
If the measured preload is less than the specification, replace
the washer of the ring gear's tooth surface side with a thicker
one.
If the preload is greater than the specification, replace the
washer of the ring gear's tooth surface side with a thinner one.
HINT:
Changing the snap ring thickness by 0.02 mm (0.0008 in.) will
change the total preload by approx. 0.1 N´m (1 kgf´cm, 0.9
in.´lbf).
