GM Corsica/Beretta 1988-1996 Repair Guide



The power rack and pinion steering system has a rotary control valve which directs the hydraulic fluid to either side of the rack piston. The integral rack piston is attached to the rack and converts the hydraulic pressure into left or right linear motion. A vane-type constant displacement pump with integral reservoir provides hydraulic pressure. No in-car adjustments are necessary or possible on the system.
