<p>A wheel nut remover has a crank lever with interchangeable sockets to fit different wheel nuts at one end, and with the other end gripped by the car jack. The vertical movement of the jack, braced against the ground, is used as a heavy duty lever to operate the crank. The remover frees stubborn wheel nuts with a minimum of manual effort. The large vertical force of the jack is converted into a torque to operate on the wheel nut.</p> |
