Abstract: The jack stand assembly includes a coupling plate with a plurality of openings for receiving the lugs of a wheel hub to fixedly attach the coupling plate with the wheel hub. The coupling plate is operably supported by a support structure which has an adjustable height. The support structure is configured to rotate about a vertical axis to allow the wheel hub to be rotated in a steering motion when the wheel hub is fixedly attached with the coupling plate. A bearing assembly is interposed between the coupling plate and the support structure to allow the wheel hub to rotate about a horizontal axis.

Abstract: A dust hoot for a moveable joint is provided. The dust boot includes a boot body disposed annularly about an axis and defining an interior cavity. The boot body has a housing opening at a first longitudinal end for attaching to a housing and a shank opening at a second longitudinal end opposite the first longitudinal end for sealingly engaging a shank portion of a ball stud of the ball and socket joint assembly. The boot body defines a plurality of longitudinal strengthening portions formed therein and extending longitudinally at an acute angle relative to the axis in a relaxed condition of the dust boot for resisting rotation of the dust boot in response to a rotation of the ball stud and for improving sealing of the dust boot with the shank portion of the ball stud.

Abstract: A vertical control arm bushing for allowing rotation of a control arm relative to a vehicle frame is provided and includes a housing extending along and annularly disposed about an axis and defining central bore extending axially therethrough. A stud has a pair of diametrically opposing end portions extending along the axis through the central bore of the housing. A pair of dust boots each includes a boot body defining an interior cavity and having a housing opening at a first longitudinal end attached to the housing and a stud opening at a second longitudinal end opposite the first longitudinal end sealingly engaging one of the end portions of the stud. The boot body defines a plurality of longitudinal strengthening portions formed therein for resisting rotation of the dust boot in response to a rotation of the stud and for improving sealing of the dust boot.
