Efficient Maneuvering with a Steering Rack

Being able to turn at the right corner at the right moment is important as this can have an effect on the safety of motorists. Thus a responsive steering is always best. To achieve this, the steering rack and other chassis components must be in top condition.

The steering rack consists of a rack enclosed with a steering pinion. Through the set of shafts and U-joints, the steering rack is linked to the steering wheel. When the steering wheel is turned, the pinion moves and pushes the steering rack either to the left or right. With the ends of the steering rack connected to them, the front wheels are able to turn.

Steering racks are used on both front-wheel drives and cars with power steering. A smoother and easier turning is achieved due to its gear reduction feature. In the case of a power steering vehicle, a steering rack with an engine-driven pump supplies high-pressure hydraulic fluid to the steering rack when the wheel is turned. Such system actually helps the steering rack turn easily.

Since the car’s performance and passenger safety are directly affected by the ability of the steering rack to turn efficiently, steering rack maintenance is important. When checking the steering rack, it is suggested to inspect the other steering parts as well, such as the power steering belt, steering fluid, steering pump, steering hoses, and ball steering gear. Motorists should also observe when a steering rack starts to become defective. It usually happens when there is difficulty to steer or the steering wheel is harder to turn and when there is fluid leakage. If one of these signs is present, it is better to check if the steering rack is already worn out or if there is no more hydraulic fluid. If the problem is beyond any of these, then the best thing to do is opt for a replacement.
