Axle Flange Face Runout

NOTE: If the axle shaft assembly is removed, check runout of the shaft itself. The forged (unmachined) part of the shaft is allowed to have as much as 3.0 mm (0.120 inch) runout. This alone will not cause a vibration condition.





1. Install Dial Indicator with Bracketry on the axle flange face, as close to the outer edge as possible. Zero the indicator to allow the pointer to deflect either way.
2. Rotate the axle shaft one full turn and note the maximum and minimum readings. The difference between the maximum and minimum readings will be the total axle flange face runout. Axle flange face runout should not exceed 0.254 mm (0.010 inch).
