(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
Total Preload (at starting):
-
When the value is outside the standard range, adjust using the differential case washer on the ring gear tooth side.
-
When the value is less than the lower limit of the standard range, replace the differential case washer with a thicker one.
-
When the value is more than the upper limit of the standard range, replace the differential case washer with a thinner one.
-
For reassembly purposes, record the measured value.
(b) Set a lever probe to a dial indicator. Insert the probe into the drain plug hole and set it onto the edge of one of the teeth of the ring gear at a
right angle.
(c) Using SST, turn the differential case clockwise and counterclockwise and measure the ring gear backlash while holding the companion flange
with your hand.
SST: 09564-50010
Standard backlash:
0.13 to 0.23 mm (0.00512 to 0.00905 in.)
-
Measure at 3 or more areas around the circumference of the ring gear.
-
If the backlash is not in the standard range, increase the LH and RH differential case washer by the same amount until the backlash is in the
standard range.
-
Record the measured value and use it when selecting the differential case washer.
-
Perform the tooth contact pattern inspection for the differential ring gear and drive pinion. The results will be used as a reference for
