Wheel Hub Flange Bolt Circle Runout

NOTE: The brake discs must be removed to perform all runout measurements.

1. Position the Dial Indicator with Bracketry perpendicular to the wheel hub bolt, as close to the hub face as possible. Zero the indicator to allow the pointer to deflect either way.





2. Rotate the hub 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 wheel hub bolt pattern runout. The runout must not exceed 0.38 mm (0.015 inch).
