Abstract: A spindle having a threaded end and a lubricated area spaced from the threaded end, the spindle having a first lubricant passageway extending from the spindle end and terminating adjacent the lubricated area and a second lubricant passageway communicating with the first lubricating passageway and the lubricated area. The spindle further having a key opening adjacent the outer end, the key opening extending through the spindle longitudinal axis and the first lubricant passageway being spaced from the axis so that grease may be inserted through the first lubricant passageway without entering the key opening. In an alternate embodiment, the passageway and key openings intersect but the lubricant passageway is larger in diameter than the diameter of the key opening so that when a key is placed in the key opening, lubricant can flow on either side of the key as it flows through the first lubricating passageway, the key being dimensioned so that substantially no lubricant flows through the key opening.
