24. ADJUST DRIVE PINION PRELOAD
Using a torque wrench, measure the preload of the backlash
between the drive pinion and ring gear.
Preload (at starting):
New bearing:
0.9
−
1.6 N·m (10
−
16 kgf·cm, 8.7
−
13.9 in.·lbf)
Reused bearing:
0.5
−
0.8 N·m (5
−
8 kgf·cm, 4.3
−
6.9 in.·lbf)
If the preload is greater than the specification, replace the bear-
ing spacer.
If the preload is less than the specification, retighten the nut a
little at a time with a torque of 13 N·m (130 kgf·cm, 9 ft·lbf) until
the specified preload is reached.
Maximum torque: 343 N·m (3,500 kgf·cm, 253 ft·lbf)
If the maximum torque is exceeded while retightening the nut,
replace the bearing spacer and repeat the preload procedure.
Do not back off the pinion nut to reduce the preload.
25. RECHECK RING GEAR BACKLASH
26. RECHECK TOOTH CONTACT BETWEEN RING GEAR
AND DRIVE PINION
27. CHECK RUNOUT OF COMPANION FLANGE
28. STAKE DRIVE PINION NUT
29. INSTALL ADJUSTING NUT LOCKS
(a)
Install 2 new nut locks on the bearing caps.
Torque: 13 N·m (130 kgf·cm, 9 ft·lbf)
(b)
After tightening bolts, bend the nut locks.
