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 10 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. 1526 14 20c 23 608 12a 12 4418a ~ -76- ' -7_6b 72Fig. 1 102 242220 70 15 12 23 70 72 Fig.g.2 14 16 12 'R 420 12a 26 76 28f 1-122f 72 70 28 12c 50f 5 2432 46 -34 24 22 48- - 24f 40 Fig. 3 12a R R2 Fig. 4
