Technician A says when driving a vehicle straight ahead, equal pressure exists on each side of the ball nut piston in a power recirculating ball steering gear. Technician B says when cornering with a power recirculating ball steering gear, torsion bar twisting positions the spool valve inside the rotary valve so fluid pressure is directed to the appropriate side of the ball nut piston. Who is correct?
