Wheel Hub Runout Inspection
Wheel Hub Bolt Circle RunoutNOTE: 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 face of the hub 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).
Pilot Runout
1. Position the Dial Indicator with Bracketry with the Clutch Housing Alignment Adapter to the pilot, as close to the face of the hub as possible. Zero the indicator to allow the pointer to deflect either way.
2. Rotate the hub one full turn and note the maximum and minimum readings. The difference between the maximum and minimum readings will be the total pilot runout. The runout must not exceed 0.15 mm (0.006 inch).
Wheel Hub Face Runout
1. Position the Dial Indicator with Bracketry on the hub face, as close to the outer edge as possible. Zero the indicator to allow the pointer to deflect either way.
2. Rotate the hub on full turn and note the maximum and minimum readings. The difference between the maximum and minimum readings will be the total face run out. The runout must not exceed 0.254 mm (0.010 inch).
