21. INSPECT DIFFERENTIAL RING GEAR BACKLASH
a. Using a dial indicator, check the backlash of the ring gear.
Backlash: 0.13 - 0.18 mm (0.0051 - 0.0071 inch)
If the backlash is not within the specification, adjust the side bearing preload or repair as necessary.
22. INSPECT TOOTH CONTACT BETWEEN RING GEAR AND DRIVE PINION (See step 63)
23. DIFFERENTIAL PINION AND SIDE GEAR BACKLASH(W/O TORQUE SENSING LSD)
a. Using a dial indicator, check the backlash of the side gear while holding 1 pinion gear toward the differential case.
Backlash: 0.05 - 0.20 mm (0.0020 - 0.0079 inch)
If the backlash is not within the specification, install the 2 side gear thrust washers of different thickness (See step 51).
HINT: Measure the backlash of the side gear with the side gear shaft installed.
24. INSPECT RUNOUT OF REAR DRIVE PINION COMPANION FLANGE SUB-ASSY REAR
a. Using a dial indicator, measure the runout of the companion flange vertically and horizontally.
Maximum runout: 0.10 mm (0.0039 inch)
25. INSPECT DIFFERENTIAL DRIVE PINION PRELOAD
a. Using a torque wrench, measure the preload of the backlash between the drive pinion and ring gear.
Preload (at starting): 0.6 - 0.9 Nm (6 - 9 kgf-cm, 5.2 - 7.8 inch lbs.)
26. INSPECT TOTAL PRELOAD
a. Using a torque wrench, measure the total preload.
Total preload (at starting): Drive pinion preload plus 0.3 - 0.5 Nm (3 - 5 kgf-cm, 2.6 - 4.3 inch lbs.)
If necessary, disassemble and inspect the differential.
