Abstract: A tool is formed of an upper component and a lower component. An intermediate component is formed of a first plate and a parallel second plate. The first plate and the second plate span the lower end of the upper component forming an upper pivot point and span the upper end of the lower component forming a lower pivot point. A foot is integrally formed with and extends r the lower component. A handle is formed of a cross piece with a central extent from the lower component adjacent to the lower end of extent central extent being attached to the upper end of the upper component.

Abstract: A cylindrical rotatable hub has interior and exterior cylindrical surfaces, an exterior end, a central extent, and an interior end. A fixedly positioned generally cylindrical spindle has an outer end and an enlarged annular inner end with a central extent axially between the outer and inner ends. Tapered inner and outer wheel bearings operatively couple the hub exteriorly and the spindle interiorly adjacent to the interior and exterior ends of the hub. The inner and outer wheel bearings are adapted to allow rotation of the hub with respect to the spindle. Lubricant input and output passageways extend through the inner end of the spindle.

Abstract: A spindle has first, second and third portions, each portion having interior and exterior surfaces, the third portion having an interiorly facing interior spindle face. A cylindrical sleeve bearing has an exterior surface in the first portion and an interior surface rotatably receiving an axle. A knuckle has an exteriorly facing exterior knuckle face positioned in contact with the interior spindle face. The knuckle has an interior knuckle face and an aperture for the passage of the axle. A lubrication assembly is formed of a channel extending through the knuckle and the spindle and the bearing sleeve and includes a lubrication fitting. The invention also includes a lubrication method.
