Who is correct? - answerNeither A nor B A technician notices during a road test for a pulling complaint that the steering wheel is slow to return to center and requires higher than normal steering effort.

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? - answerBoth A and B Power rack and pinion steering gear operation are being discussed. Technician A says the position of the rotary valve inside the spool valve directs the fluid to the appropriate side of the rack piston.
