Steer Clear of Power Steering Problems (Power Steering Maintenance)

We usually take our vehicle's easy steering for granted until something goes wrong.  Power steering is what makes it almost effortless to turn the steering wheel, aiming your vehicle in the direction you want to go. Without the assistance of power from the engine, steering would be a laborious process, so you want to make sure the system is working well.

Power steering systems are usually one of two types, hydraulic and electric.  The hydraulic type uses a pump that is driven by either a belt or an electric motor.  This system uses hydraulic fluid to create pressure that gives your steering the power assist.  Since that pump is always working, time and distance traveled eventually take their toll, and these systems need to be periodically inspected.  Also, while that hydraulic fluid can last for years, it should be replaced periodically as it degrades over time. Your vehicle's owner's manual contains the manufacturer's recommendations.

A technician can check for leaks in the hoses, pump housing or reservoir.  Also, the belts should be inspected and so should the pump, as these can fail.  Signs of a failing pump are a groaning noise when you turn the steering wheel, stiff steering, squealing noises when you first start your car and puddles of a reddish-brown fluid under your vehicle. 

The other type is called EPS, or electric power steering, which is becoming more commonly used in the latest vehicles.  It only delivers power assist when you need it and has an electric motor that supplies that steering help.  It's more efficient, accurate, compact and clean. And because it has a lot fewer components, it's easier to maintain. 

If you have electric power steering, you may notice sometimes it's hard to turn the wheel or your Check Engine light comes on.  Sometimes the power assist motor fails or there can be problems with electrical connections.  Any time you have symptoms, it's important for your safety and that of drivers around you that you have a technician check them out.

Properly working brakes are essential for the safe operation of any vehicle.  Stop! And make sure yours are working properly.

All Lined Up (Alignment Inspection)

When you head down a straight road, does your vehicle pull to one side?  Do you feel vibration in any of the wheels? If you've noticed any of these things, it's probably time for you to get your wheel alignment checked.

When your vehicle left the factory, its wheels were parallel to each other and perpendicular to the ground.  That maximizes traction for good steering and braking. Every time you take your vehicle on the road, normal wear and tear will affect your alignment. Hit a bump, a pothole or a curb and all those little knocks will add up

Bad alignment not only can cause your steering wheel to pull unevenly, it can also wear your tires out a lot faster than they should. In fact, if you look at your tires and see one side of the tread is a lot smoother than the other, it could be another sign of bad alignment.

Since different problems can cause similar symptoms, the first thing our trained technician will do is test drive your vehicle. Then, they'll check the front end and steering linkage as well as look for tire wear.  Then, the technician will put your vehicle on a lift and use computerized diagnostic equipment to measure alignment angles so they can precisely align your vehicle's components.

There are different kinds of alignments.  One is a front-end alignment that aligns components of the vehicle's front axle.  Another is a thrust alignment that makes sure the front wheels are lined up with the direction the rear wheels are pointed.  A third type is four-wheel alignment which is usually used on all-wheel drive and  4-wheel drive vehicles.  It's also recommended for front-wheel drive vehicles that have independent rear suspensions.  It makes sure the angles of all the wheels are where they should be relative to each other and also the vehicle's body or frame.

Your steering wheel should be perfectly centered if you are heading straight down the road, so the technician will adjust it so it is. Finally, they'll take your vehicle back on the road for a final test drive to make sure it's performing the way engineers intended.

Your service adviser can recommend how often you should have your alignment inspection, since it depends on the type of vehicle you drive (SUV, sporty car, etc.) and your driving environment.  Properly aligned wheels can help your vehicle perform better and save you from expensive repairs down the road.
