Patent ID: 8881329

Claim:
A kit for installing and removing road wheels from a motor vehicle, comprising: a first jack capable of being mounted to the body of the motor vehicle and operated from the electrical system of the motor vehicle, for assisting the operator of the motor vehicle to raise the motor vehicle above the ground on which the motor vehicle rests and to lower the motor vehicle to the ground, comprising: a housing having mounting apparatus for mounting the housing permanently to the motor vehicle; a first screw jack assembly and a second screw jack assembly each mounted within the housing and respectively comprising a jack screw having external threads and a rotational axis, a motor operably connected to the jack screw in a manner enabling the motor to rotate the jack screw about the rotational axis, a first arm drivably engaging the jack screw and disposed to project progressively from the housing when the jack screw is rotated in a first direction and to be progressively retracted into the housing when the jack screw is rotated in an opposed second direction; a second arm pivotally connected to the housing and disposed to project progressively from the housing when the jack screw is rotated in the first direction and to be progressively retracted into the housing when the jack screw is rotated in the opposed second direction; a foot which is pivotally connected to the first arm and the second arm and which contacts the ground below the vehicle when the first arm and the second arm project sufficiently from the housing, whereby the vehicle is lifted above the ground; an electrical system including a manual controller enabling the operator of the motor vehicle to selectively operate the first screw jack assembly and the second screw jack assembly to raise the motor vehicle above the ground and to lower the motor vehicle to the ground; and a lug threading tool disposed to tighten and loosen lug nuts and screws of the wheel of the motor vehicle, comprising a frame, a plurality of drive sockets mounted to the frame, a common drive which rotates all of the drive sockets in the same direction when the common drive is rotatably driven, a motor disposed to rotatably drive the common drive, and a clamp disposed to engage the wheel of the motor vehicle, whereby the powered lug threading tool is supported on the wheel, wherein the drive sockets may each engage one lug nut or screw of the wheel such that all of the lug nuts or screws are engaged and simultaneously loosened and tightened when the common drive rotates the drive sockets.
