Power steering, common in most late model cars, helps you easily turn your cars wheels. It may just provide a helpful push or it may do all the work itself in response to the motion of the steering wheel. Either way, turning a vehicle requires less effort than it otherwise would. It plays a vital role in the way that your car handles and it is important to maintain it on a regular, albeit infrequent basis.
Power Steering Service Warranty
Exit5 Auto Group is proud to be a BG Product Partner. That means we can offer the Lifetime BG Protection Plan™ if your vehicle has less than 75,000 miles. Simply perform the service every 30,000 miles and the Protection Plan will be in effect as long as you own your car!
Why perform a Power Steering service?
The power steering pump produces high pressure up to 2000 pounds, with high heat. This leads to fluid breakdown and failure. Symptoms include groaning and whining noises, erratic steering and pump leaks.
What does the service do?
A powerful cleaner suspends and dissolves varnish and gums in the power steering system and then all of the old fluid is replaced with new high-tech power steering fluid for both conventional sector and rack and pinion. The benefit will be a quieter-operating, longer lasting power-steering system.
Simply put, performing a Power Steering service will provide you with the following benefits.
- Eliminate steering squeal
- Correct jerky steering wheel
- Prevent fluid leak
- Reduce steering component wear
Components and Design
Automotive power steering systems vary greatly in design, but a typical hydraulic setup includes the following:
- A sensor attached to the steering wheel that detects force or torque — in effect, the system “knows” when the driver turns the steering wheel and the car’s wheel haven’t caught up yet, so the system can provide assistance when it’s needed.
- A pump, driven by the car’s engine (usually by means of a belt), to raise the pressure in the power steering fluid up to as much as 100 times atmospheric pressure.
- A collection of valves that direct the high-pressure fluid through hoses or metal tubes to one side or the other of the steering system according to how the steering wheel has been turned.
- Actuators with which the high-pressure power steering fluid helps push the front wheels to one side or the other (the details depending on whether the vehicle has rack-and-pinion or recirculating ball steering).
Electric power steering systems work differently but achieve similar results.
