A tire stabilizer is provided that includes an upper block, a lower block, and a biasing device. The upper block has an inclined surface that is inclined relative to a bottom surface. The biasing device is disposed between the upper block and the lower block. A method of rotating a lug nut of a vehicle that is elevated above a ground surface is also provided. The method includes positioning a tire stabilizer between the ground surface and a tire of the vehicle, placing a wrench over the lug nut, rotating the wrench, removing the wrench from the lug nut, and removing the tire stabilizer from the tire. The tire stabilizer includes an upper block having an inclined surface, a lower block partially disposed within the upper block, and a biasing device disposed between the upper block and the lower block.

In the context of service and maintenance of heavy road vehicles, apparatus is provided that is configured to engage and support a rack and manoeuvre it into position relative to the vehicle to facilitate removal and installation of the wheels. The rack has a frame with a base and a pair of arms, each arm being pivotally attached to opposite sides of the base to pivot between an open configuration and a folded configuration. The apparatus may be expanded and contracted between an expanded configuration, where the rack engagement assembly is configured to engage the rack in the open configuration, and a contracted configuration where the rack engagement assembly is configured to engage the rack in the folded configuration.

The embodied invention is a two tire lift tower and platform that is movable on castors. A motorized belt system is used to lift the tires. The belt system is mounted on each tower and is connected to a horizontal tire lifting bar. It is designed for portability by using a rechargeable battery is mounted on a rotating frame that allows each tire to be lifted separately. Simple buttons operate the tire belt lifting design that also allows for motor speed control to be adjusted by the operator. The dual belt system ensures that the horizontal lift bar is adequately maintained in a horizontal orientation. The maintenance of the unit is relatively simple due to the simplified design.

A driving device for use in a hub assembly includes a stationary ring, a connecting seat and a pawl unit, all of which surround an axis. The stationary ring has a plurality of angularly spaced-apart ratchet grooves that are symmetric. The connecting seat has a sprocket and at least one connecting portion, both of which are arranged along the axis. The pawl unit includes a ring-shaped coupling seat that is removably sleeved on the connecting seat and that has at least one coupling portion engaging removably the at least one connecting portion, and a plurality of angularly spaced-apart retaining grooves, each retaining a pawl and a resilient member for engaging a corresponding one of the ratchet grooves of the stationary ring.
