Claim 7:
8. A method of using an expandable car jack, the expandable car jack having a hinged section and a base section at a bottom of the hinged section, the base section including a base support coupler that passes through a first base support member and a second base support member, the method comprising:
disengaging a first threaded portion of the base support coupler from a first base support member, wherein a second threaded portion of the base support coupler is engaged with the second base support member;
rotating the first base support member with respect to a second base support member from a parallel alignment to a perpendicular alignment;
while the first base support member and the second base support member are in the perpendicular alignment, moving the second base support member into a nested configuration with the first base support member; and
mechanically engaging the second threaded portion of the base support coupler with the first base support member so that the base support coupler prevents the first base support member from rotating with respect to the second base support member.
