    If the flange runout exceeds 0.25 mm (0.010 in), remove the pinion flange, reindex the flange 1-half turn on the pinion, and reinstall it.

  8. Check the runout again. If necessary, rotate the flange until an acceptable runout is obtained. If the flange runout is still more than 0.25 mm (0.010 in), install a new pinion flange.
