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.
3. CHECK RING GEAR BACKLASH
Using a dial indicator, measure the ring gear backlash. Backlash: 0.15 − 0.20 mm (0.0059 − 0.0079 in.)
HINT:
Perform the measurements at 3 or more positions around the
circumference of the ring gear.
If the backlash is not within the specification, adjust the side
bearing preload or repair as necessary.
4. MEASURE DRIVE PINION PRELOAD
(a) Using a torque wrench, measure the preload of backlash between the drive pinion and ring gear.
Preload (at starting):
0.7 − 1.0 N·m (7 − 10 kgf·cm, 6.1 − 8.7 in.·lbf)
(b) Using a torque wrench, measure the preload. Total preload (at starting):
Drive pinion preload plus
w/o Differential lock
0.4 − 0.6 N·m (4 − 6 kgf·cm, 3.5 − 5.2 in.·lbf)
w/ differential lock
0.3 − 0.7 N·m (3 − 7 kgf·cm, 2.6 − 6.1 in.·lbf)
If necessary, disassemble and inspect the differential.
