Lateral RUNOUT

  1. Tighten spindle nut to eliminate bearing end play. Ensure that rotor can be turned. Install and tighten lug nuts. Attach dial indicator on suspension, with indicator tip on face of rotor. When checking runout on rear disc brakes ("F" Series Super Duty only), make sure rear axle bearings are adjusted properly.
  2. Set dial indicator to zero, slowly turn rotor, and note high and low readings on dial. Runout must not exceed specifications. See DISC BRAKE SPECIFICATIONS  . Resurface or replace rotor as required.
