Service to a vehicle's power steering system is part of preventive maintenance for  Commerce auto owners. This system provides power to the steering wheel so you can turn it with ease. Without power steering, all of the power to turn your vehicle's wheels would have to come from you.

The central element of most power steering systems is a pump. The pump pressurizes the power steering fluid, and it is this pressure that provides auxiliary steering power. A belt connected to the engine usually powers the pump, although some systems use an electric pump. Some newer vehicles have an electric motor that directly provides the power steering boost.

Pressurized fluid moves from the pump to the steering gear through a high-pressure hose. A low-pressure hose returns fluid to the pump. Power steering fluid cleans, cools and lubricates the system.

Commerce drivers should remember that fluid levels in the power steering system should be checked at every oil change. Low fluid levels can damage the pump, which can be expensive to repair. Low fluid levels may also indicate a leaky hose in the power steering system, so it is a good idea to inspect the hoses, especially if your fluid levels are low.

Power steering fluid breaks down over time, losing its effectiveness. It also gradually collects moisture, which can lead to corrosion in the steering system. So the fluid needs to be replaced occasionally. You should check with your owner's manual or ask your service advisor at Commerce Auto Repair to learn how often this fluid should be replaced.

When your fluid is replaced, your technicians at Commerce Auto Repair will remove the old fluid and replace it with new. Power steering fluids are not all created equal; the fluid has to be compatible with your hoses and seals. Commerce Auto Repair can ensure that you get the right fluid for your vehicle, or you can consult your owner's manual.

Signs that your power steering system is in trouble can include the following: a steering wheel that is hard to turn, auxiliary steering power that cuts in and out, or a whining sound coming from the pump. Also, drivers in Commerce who are not topping off the power steering fluid on schedule may hear squealing coming from the engine belts.

To protect your steering system you should never hold the steering wheel in the far right or far left position for more than a few seconds at a time. This can wear out your pump in a hurry.

Preventive maintenance for your steering system primarily involves the power steering components, but your steering system has other parts that can wear out or be damaged by rough Michigan driving conditions. Such parts include the ball-joint, idler arm, steering gear, steering-knuckle and tie rod. Signs that they are in need of attention include play in the steering wheel, a vehicle that wanders, uneven tire wear and a steering wheel that is off-center. Commerce drivers should have their alignment checked annually. This check-up can reveal bent or damaged steering components.
