INSPECTION
1. INSPECT REAR AXLE SHAFT
a. Using a dial indicator, measure the runout of the shaft and flange.
Maximum shaft runout: 2.0 mm (0.079 inch)
Maximum flange runout: 0.1 mm (0.0040 inch)
If the rear axle shaft or flange are damaged or worn, or if runout is greater than the maximum, replace the rear axle shaft.
