Abstract: A device and method for preloading a transmission shaft assembly is disclosed. The transmission having the device of the present invention generally has a plurality of gears for providing a plurality of speed ratios. The shaft assembly has a first shaft, a first sleeve shaft, a second sleeve shaft and a first fastener. The first shaft has a flange end and an adjustment end. The first sleeve shaft is concentric with the first shaft and has a first end. The first end of the first sleeve shaft is in communication with the flange end of the first shaft. The second sleeve shaft is concentric with the first shaft and is axially aligned with the first sleeve shaft. The second sleeve shaft has a first end. The plurality of synchronizers for selectively connecting at least one of the plurality of gears to at least one of the first and second sleeve shafts. The first fastener is engagable with the adjustment end of the first shaft and is configured to move axially on the adjustment end.

Abstract: A support member (14) for rotatably coupling a first element to a second element. The support member includes a sleeve (50) for rotatably supporting the first element, and a flange (56) having a concave central portion. The flange (56) is coupled to the sleeve (50). The flange (56) has bearing surfaces (68a, 68b) formed thereon along which the flange (56) is mounted to the second element. In one embodiment, the first element is a spindle (12) of a vehicle wheel assembly (11) and is rotatably supported in the sleeve (50) by rollable bearing elements positioned therein. Multiple tapered lobes (64) extend outwardly from the sleeve (50), and the support member (14) is mounted to a vehicle via bearing surfaces (68a, 68b) along the lobes (64).
