A stabilizing jack includes a base securable to a vehicle frame with a drive screw rotatably mounted to the base and a screw follower threadingly secured to the drive screw. A length adjustable lift leg is pivotally connected at an upper end to the screw follower. A stabilizing member is pivotally connected at a first end to the base inward from the screw follower. The lift leg is pivotally connected at an outer end to the stabilizing member. Downward extension of the lift leg through outward advancement of the screw follower on the screw and downward pivoting of the lift leg by the stabilizing member advances the foot into the ground to raise the vehicle frame relative to the suspension. The extended lift leg and stabilizing member form a triangle with the base providing resistance to lateral movement of the vehicle frame relative to the wheels and suspension. -82 -67
