Lateral Runout (Front & Rear Disc)

  1. On front disc brakes, tighten wheel bearing adjusting nut to eliminate bearing end play. Ensure rotor can be rotated by hand. When checking runout on Excursion and Super Duty Pickup rear disc brakes, make sure rear axle bearings are adjusted properly.
  2. Once adjusted, DO NOT change rear bearing setting. Attach dial indicator to suspension, with indicator tip set 1" from outer edge of rotor face. Set dial indicator to zero, and slowly turn rotor. Take reading within a 6.00" (152.4 mm) radius on rotor. Runout must not exceed specification. See DISC BRAKE SPECIFICATIONS  table. Resurface or replace rotor as required.
