DISASSEMBLY
1. CHECK RUNOUT OF COMPANION FLANGE
Using a dial indicator, measure the vertical and lateral runout of
the companion flange. Maximum runout: 0.10 mm (0.0039 in.)
2. CHECK RING GEAR RUNOUT
Using a dial indicator, measure the ring gear runout. Maximum runout: 0.10 mm (0.0039 in.)
If the runout is greater than the maximum, replace the ring gear
and driven pinion as a set.
3. CHECK RING GEAR BACKLASH
Using a dial indicator, measure the ring gear backlash. Backlash: 0.13 −0.18 mm (0.0051 −0.0071 in.)
If the backlash is not within the specification, adjust the side
bearing preload or repair as necessary.
4. MEASURE DRIVE PINION PRELOAD
Using a torque wrench, measure the preload of backlash be-
tween the drive pinion and ring gear. Preload (at starting):
0.5 − 0.8 N·m (5 − 8 kgf·cm, 4.3 − 6.9 in.·lbf)
5. CHECK TOTAL PRELOAD
Using a torque wrench, measure the preload. Total preload (at starting):
Drive pinion preload plus
0.4 − 0.6 N·m (4 − 6 kgf·cm, 3.5 − 5.2 in.·lbf)
If necessary, disassemble and inspect the differential.

(e) Install the pinion gear with the spider to the RH case.
(f) Using a dial indicator, holding the side gear and spider and measure the side gear backlash.
Backlash: 0.05 − 0.20 mm (0.0020 − 0.0079 in.)
HINT:
Measure at all 4 locations.
Measure the backlash at the RH case and at the LH case.
If the backlash is not within the specification, install a thrust
washer of a different thickness. Thrust washer thickness
