* If preload is greater than specification, replace the
bearing spacer.
* If preload is less than specification, retighten the
nut 5 ± 10
° at a time until the specified preload is
reached.
If the maximum torque is exceed while retightening the
nut, replace the bearing spacer and repeat the preload
procedure. Do not back off the pinion nut to reduce the
preload.
