< Turning torque of spiral bevel pinion shaft >
1. Install the spiral bevel pinion shaft assembly only
to the front axle case.
2. Measure the turning torque of the spiral bevel
pinion shaft.
3. If the turning torque is not with in the factory
specifications, adjust with lock nut.

spline of spiral bevel pinion shaft.
2. Measure the backlash be moving the spiral bevel
pinion shaft by hand lightly.
3. If the backlash is not within the factory
