(continued)
Lubricate the hub pads or the wheel hub bore generously with a non-water-based
lubricant.
Before installing two-piece flange nuts, lightly lubricate the stud threads and the contact surfaces
between the cap nut and the washer as illustrated below with an SAE 30W oil. This will minimize cor-
rosion between the mating surfaces. Lubrication is not necessary with new hardware.
Position one of the hub’s pilot pads at the twelve o’clock position. After positioning wheels on the
pilot pads, hand tighten all two-piece flange nuts, then tighten to the recommended torque following
the proper sequence shown below for your type wheel. After 5-50 miles of operation torque should be
rechecked, unless your documented fleet practices determine otherwise. Check torque frequently from
then on. If nuts require frequent tightening, studs break frequently, or wheel bolt holes are pounding
out, hardware and mounting practices should be reviewed.
