Drive wheels use a single oil-seal assembly.
They are lubricated from the oil supply in the
differential housing. Bearings are tapered rollers,
adjustable to compensate
differential oil level with general-purpose gear
lubricant (refer to Section 24 "Lubrication" for
proper oil grade selection) to ensure adequate oil
supply to wheel bearings at all times.
