NOTE:

This measurement procedure is intended to measure propeller shaft runout for prop shaft systems with 2 or 3 U-joints only. This is not for prop systems with only 1 U-joint or with only constant velocity (CV) joints, and/or coupler assemblies.
When measuring runout of propeller shafts, do not include fluctuations on the dial indicator due to welds or surface irregularities.
Always inspect the runout of any replacement propeller shaft.
