A wheel mount for a wheel comprises a spindle, a hub for surrounding the spindle and a bearing assembly interposed between the spindle and the hub. The spindle extends from an end of an axle of a vehicle and has a generally decreasing diameter from its proximal end to its distal end. The spindle is provided with a pair of lands near the ends of the spindle for receiving bearings, and has bearing retainers near the respective ends also, the distal retainer being removably attached. These inboard and outboard bearing retainers define an axial bearing space. The hub has a central aperture with an inboard land and an outboard land provided on an internal surface of the central aperture, also for receiving bearings. The bearing assembly comprises an inboard bearing and an outboard bearing in spaced apart relationship within the axial bearing space. The inboard bearing has an internal diameter larger than the internal diameter of the outboard bearing. The bearing assembly further has a conical shim placed in frictional fit between the cone portions of the inboard and outboard bearings and holding the respective bearings in the spaced apart relationship.

[ What is claimed is:] [1.] A mount for a wheel of a vehicle comprising:a spindle extending from an end of an axle, said spindle generally decreasing in diameter from a proximal end thereof to a distal end thereof and provided with an inboard land near the proximal end and an outboard land near the distal end, the spindle further having an inboard bearing retainer near the proximal end and an outboard bearing retainer near the distal end, said inboard and outboard bearing retainers defining an axial bearing space;a hub surrounding said spindle, said hub having a central aperture with an inboard land and an outboard land provided on an internal surface of the central aperture;a bearing assembly interposed between the spindle and the hub, the bearing assembly having an inboard bearing and an outboard bearing in spaced apart relationship within the axial bearing space, the inboard bearing having an internal diameter larger than an internal diameter of the outboard bearing, each of the bearings comprising a cylindrical cone with an outer raceway, a cylindrical cup with an inner raceway and a plurality of tapered rollers circumferentially spaced in a cage mounted in the raceways;a conical shim, interposed between the cylindrical cones of the inboard and outboard bearings; andan annular grease seal is mounted within the axial bearing space on the inboard side of the inboard bearing between the cup and the cone.
