Claim 17:
18. A compact power running board assembly adapted for connecting to a sport utility vehicle, comprising:
a linear actuator assembly operably coupled to a swing arm of a linkage;
a running board operably connected to said linkage;
a housing assembly including an opening;
a pivot shaft within said housing assembly, said swing arm extending through said opening of said housing assembly and operably mounted to said pivot shaft;
a motor assembly operably coupled to said linear actuator assembly for driving said linear actuator assembly to move said running board between at least one stowed position and at least one deployed position;
a first bushing bearing coupled to said pivot shaft within said housing assembly at a location below said swing arm; and
a second bushing bearing coupled to said pivot shaft within said housing assembly at a location above said swing arm;
at least one thrust bearing immediately adjacent to said swing arm to transfer force from said swing arm to said first bushing bearing;
wherein said swing arm located between and a predetermined distance from said first and second bushings within said housing assembly provides a compact arrangement and reduces reaction forces within the housing assembly by at least half.
