A seat adjustment assembly for driving a vehicle seat forwardly and rearwardly within a cab of a vehicle includes a pair of lead screws which are driven by cables from a single motor. The lead screws engage a nut runner, and the nut runner is fixed to the lower track. The lead screws are fixed to the upper track, and when the lead screws rotate, the nut runner causes the lead screw to move axially. This thus causes the upper track relative to the lower track, and move the seat. The adjustment assembly is a modular unit which can be attached as an pre-assembled to the remainder of the vehicle seat. The housings incorporated into this arrangement are staked together, such that separate retaining members such as bolts are eliminated.
