A lift truck includes systems and methods for improved stability control while turning, including a rotatable drive unit having a steerable drive tire. A first slide mechanism is coupled to the rotatable drive unit, and a second slide mechanism is mounted to a caster plate. A steering mechanism coupled to the rotatable drive unit is moved to steer the steerable drive tire, causing the first slide mechanism to interact with the second slide mechanism and to produce a downward pressure and/or reduce the downward pressure on a caster mounted to the caster plate.
