    Runout limit: 0.1 mm (0.004 in) 

  5. If the runout value is outside the repair limit, follow the procedure below to adjust.
  1. While changing the phase between companion flange and drive pinion gear by 90° at a time, check runout and determine which phase angle minimizes the runout.
  2. If the runout value is still outside of the limit after the phase has been changed, replace the companion flange.
  3. If the runout is out of the specification after replacement of companion flange, adjust the assembly status of the pinion bearings and drive pinion gear, or replace the pinion bearings.
