CHECK 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:
1.1 – 1.7 N·m (11 – 17 kgf·cm, 9.6 – 14.8 in.·lbf)
Reused bearing:
0.6 – 0.9 N·m (6 – 9 kgf·cm, 5.2 – 7.8 in.·lbf)

If the preload is greater than the specification, re-
place the bearing spacer.
S
If the preload is less than the specification, retorque
the nut with 13 N·m (130 kgf·cm, 9 ft·lbf) of torque
at a time until the specified preload is reached.
Torque: 235 N·m (2,400 kgf·cm, 174 ft·lbf) or less
S
If the maximum torque is exceeded while retighten-
ing the nut, replace the bearing spacer and repeat
the preload adjusting procedure. Do not loosen the
pinion nut to reduce the preload.
