The pressure of the working fluid in the power steering is created by a vane-type pump, which is mounted on the engine bracket and driven by a poly V-belt from the crankshaft pulley. The bypass valve installed in the pump maintains the required pressure of the working fluid in the power steering depending on the engine crankshaft speed. The power steering reservoir is installed in the engine compartment on the right side and is connected by hoses to the power steering pump and to the working fluid return line. If the power steering fails, the ability to control the car is retained, but the force on the steering wheel increases.
The steering rods are attached to the steering rack with ball joints. The steering rod ends are attached to the steering knuckles of the front suspension with ball joints. The steering rod is secured with a nut to prevent it from turning in the end. The toe-in of the steered wheels is adjusted by rotating the steering rod in the ball joint relative to the end.
