Standard backlash:
0.08 to 0.13 mm (0.0031 to 0.0051 in.)
NOTICE:
Measure at 3 or more areas around the circumference of the ring gear.
(g) If the backlash is small even in one place, replace the ring gear tooth side differential side gear shaft snap ring with a thicker one.
HINT
*
Record the measured value, as it is used to select the differential side gear shaft snap ring.
*
Perform the tooth contact pattern inspection for the differential ring gear and drive pinion. The results will be used as a reference
for selecting the differential side gear shaft snap ring.
*
When adjusting the backlash, adjust to within 0.1 mm of the average of the measurements.
(h) Remove the 2 bolts and SST from the differential carrier.

DIFFERENTIAL: DIFFERENTIAL CARRIER ASSEMBLY: REASSEMBLY
14. ADJUST TOTAL PRELOAD
(a) Using SST and a torque wrench, measure the preload with the teeth of the drive pinion and ring gear in contact.
SST : 09229-55010
Standard total preload (at starting):
New bearing
1.58 to 3.07 N*m (16.1 to 31.3 kgf*cm, 14.0 to 27.2 in.*lbf)
Reused bearing
0.86 to 2.07 N*m (8.8 to 21.1 kgf*cm, 7.6 to 18.3 in.*lbf)
(a) If the measured preload is below the standard value, replace the differential side gear shaft snap ring with a thicker one.
If the measured preload is above the standard value, replace the differential side gear shaft snap ring with a thinner one.
NOTICE:
*
If the thickness of the differential side gear shaft snap ring changes 0.02 mm, the total preload will change approximately 0.1 N*m
(1.0 kgf*cm).
*
For reassembly purposes, record the measured value.
(b) Place a dial indicator on the tip of the ring gear tooth at a right angle.
