A spindle assembly includes a spindle with a blind bore extending along the spindle axis from the drive gear towards the outer end to reduce spindle weight and provide a lubrication reservoir in the spindle. Cross-formed holes extend from the blind bore through to the bearing surface of the spindle. Lubricant from the spindle bars passes into the bore where it is stored and distributed to the journal areas through the small metering apertures. A very low friction seal between the outer bushing and dust collar is pressed into the spindle nut and seals against the polished chrome spindle surface. The seal allows a slight amount of lubricant passage outwardly from the bushings while limiting inward movement of dust towards the bushings.
