WARNING: This page is about a different car, the 2005 Ford RV Cutaway, 2005 Ford Econoline, 2005 Ford E450 Super Duty, and 2005 Ford Cutaway. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The brake discs or drums must be removed to carry out all runout measurements.
  1. Position the Dial Indicator Gauge with Holding Fixture perpendicular to the axle flange bolt, as close to the flange face as possible. Zero the indicator to allow the pointer to deflect either way.

  2. Rotate the flange until the next bolt is contacted. Record the measurement and continue until each bolt is checked. The difference between the maximum and minimum contact readings will be the total axle flange bolt pattern runout. The runout must not exceed 0.13 mm (0.005 inch)
