For many modern automobiles, the preferred steering system is the rack and pinion steering. It provides precise control and response, offering the driver a better handling experience. However, like any other component, the rack and pinion steering system can wear over time and may require replacement or repair.

What is Rack Pinion Steering?

Rack and pinion steering is a mechanism that converts the circular motion of the steering wheel into linear motion to provide steering. It functions with the help of a rack and pinion gear set, a simple device that translates rotational motion into linear motion.

Components of the System

The rack and pinion system consists of multiple components such as universal joints, main and intermediate shafts, and the centerpiece – the steering rack or gearbox.

Functionality of the System

The rack pinion steering system operates slightly differently from its manual counterpart. Part of the rack contains a cylinder with a piston in the centre, attached to the rack itself. Two fluid ports exist on either side of the piston, and a torsion bar directs a rotary valve connected to the steering wheel. When the wheel isn’t turned, power steering fluid is directed around the rotary valve and out to the reservoir, maintaining equal pressure on both sides of the piston.

How Rack Pinion Steering Works

As the steering wheel turns, the torsion bar twists, rotating the rotary valve. This action blocks the port to the reservoir, and fluid flows through an opening to one side of the steering gear. Simultaneously, the other side of the cylinder vents to the reservoir. This imbalance of fluid pressure causes the piston and, by extension, the rack, to move, causing the wheels to turn.

The power steering pump ensures adequate fluid flow when the engine is idling. It moves more fluid than necessary when the engine runs at higher speeds and contains a pressure relief valve to prevent pressure from getting too high during these periods.

Repairing and Maintaining Your Rack Pinion Steering

Occasionally, the steering rack or gearbox may wear out and require a repair or replacement. It’s crucial to service this vital component promptly to avoid significant mechanical overhauls.

The repair process involves various steps, including raising the front wheels off the ground, draining the reservoir of contaminated power steering fluid, and replacing it with the manufacturer-specified power steering fluid. Other steps include checking for leaks and ensuring the power steering pump doesn’t make any ‘whining’ or ‘growling’ noises, which indicate trapped air in the system.
