Many St. Louis drivers have been hearing about new advances in power steering technology, specifically, electric power steering. Some very high-end cars have been featuring electric power steering for a few years. An electric motor directly provides the power assist to make steering easier. Undoubtedly we’ll see much more of this in St. Louis as full electric cars and electric hybrids become more common.

The vast majority of cars and trucks serviced at Master Auto Repair in St. Louis use a hydraulic power boost system. With hydraulics, fluid is pressurized by a pump which actuates a hydraulic cylinder to reduce steering effort. Some of these pumps are powered by an electric motor. Most pumps are powered by the serpentine belt driven by the engine.

Power steering fluid has the necessary hydraulic properties and the ability to lubricate the internal parts. The power steering fluid also protects sedan components from rust and corrosion.

St. Louis car owners should be aware that manufacturers recommend that the fluid be replaced on schedule. At Master Auto Repair, the old fluid is drained and the system cleaned thoroughly. Fresh fluid is then installed.

Unfortunately, many St. Louis people don’t realize how important it is to service their power steering, or even that it should be done at all. A neglected power steering system can develop leaks and the pump won’t last as long.

Signs that you may be having problems with your power steering include the need to constantly add power steering fluid, a loud whining from the pump, erratic power assist or high steering effort. If you’re experiencing any of these problems, have your power steering checked out at Master Auto Repair in St. Louis.

In addition to the pump and hydraulic system, there are mechanical parts in the steering system. The rods, arms, joints and knuckles that actually turn the wheels can become worn or damaged. A standard alignment service includes an inspection of steering components.

If you notice any play in the steering wheel, that the steering wheel is off center, or a noise coming from your front wheels, especially when turning, have your Master Auto Repair advisor do an inspection so the problem can be corrected. Waiting too long could cause uneven tire wear and may even lead to steering failure. Call Master Auto Repair today at call one of our shops.
