DRIVE PINION RUNOUT

1.

Set a dial indicator (A) vertically to the tip of the drive pinion.

2.

Rotate drive pinion to check for runout.

3.

If the runout value is outside of the limit, possible causes are an
assembly malfunction of drive pinion and pinion bearing and
malfunction of pinion bearing. Check for these items and repair if
necessary.
