Narrative:

Low gross weight/aft cg rejected takeoff runway 13R. During taxi the aircraft was somewhat difficult to turn but I attributed this to the aft cg. Holding short of 13R we were cleared for takeoff. Aligned the aircraft with the runway centerline; again with some difficulty. Started the takeoff roll; set 70% N1 then pushed to/GA. Almost immediately the aircraft veered hard to the left. I unsuccessfully tried to use rudder steering to align the aircraft. The first officer called 'brakes; brakes' I immediately applied full braking and idle thrust and disconnected the auto throttle. I never went into reverse thrust as we were at a very slow speed; approx. 10 knots. Although I was slow to initiate the reject the aircraft came to a stop on the runway but near the left edge and angled away from centerline. Since I was unsure of how close we were to the runway edge or location of any obstacles/signs; I had the first officer inform the tower that we would need a tug to remove us from the runway. I deemed this was a safer course of action.need to always be ready for a reject even at 5-10 knots.

Title: B747-400 flight crew reported they rejected their takeoff when they had difficulty with directional control because the left body gear steering had failed.
