(c) Using a dial indicator, measure the backlash of one
pinion gear while holding the side gear toward the
case.
Standard backlash: 0.05 - 0.20 mm
(0.002 - 0.0079 in.)
HINT: Do not place in a vise the surface of the center
differential case which comes in contact with the bushing.
Referring to the table below, select the thrust washer
which will ensure that the backlash is within specification.
Try to select a washer of the same size.
(d) Using snap ring pliers, install the shaft snap ring.
5. CHECK AND ADJUST CENTER DIFFERENTIAL SIDE
GEAR THRUST CLEARANCE
(a) Install the differential side right gear.
HINT: Do not install the conical spring washer.
(b) Install the center differential case.
