Abstract: Bearing and shaft assemblies include a shaft with at least one depressed region. A first one-way bearing can be positioned on the shaft in a manner such that the first one-way bearing facilitates clockwise rotation and resists counterclockwise rotation. A second one-way bearing can be positioned on the shaft in a manner such that the second one-way bearing facilitates rotation in the second direction and resists rotation in the first direction. The first one-way bearing and the second one-way bearing can be displaced axially along the shaft so the first one-way bearing, the second one-way bearing, or both one-way bearings is/are positioned around the one or more depressed regions of the shaft to facilitate rotation in one direction, both directions or neither direction, as described herein. Other aspects, embodiments, and features are also included.

Abstract: A device for use in the installation of a tire wheel assembly onto the axle of a jacked vehicle. The device consists of two end supports connected by two parallel bars each of which contains a roller-slider assembly. The device also contains a telescoping alignment wand mounted between the parallel rods. After the alignment wand is used to position the device, the tire is placed on the roller-sliders and pushed toward the axle hub. The tire is rotated to align the wheel with the axle's lug bolts and the wheel is pushed onto the lug bolts. The tire wheel assembly may then be fastened to the axle.
