For drivers, S stands for safety.  And there are three other words that start with S that are all equally important: starting, stopping and steering. For your vehicle to be at its safest, all three functions must be in top shape.  Steering is one of those things we take for granted.  After all, you turn the wheel and your vehicle changes direction. But sometimes you might notice your steering is a little off.  Maybe you've noticed you turn your wheel slightly and your vehicle doesn't turn. You may feel a little vibration in the wheel that increases when you go faster.  You may hear a little squeak from the wheels when you steer and you may notice your tires aren't wearing evenly. These are signs that your tie rod ends may be failing. Tie rod ends help connect your vehicle's steering mechanism to the wheels.  They can wear out after you've hit one too many potholes or just from constant use.  They can cause sloppy steering and loose handling, and they ... read more

If your vehicle creaks and squeaks when you drive down the road, it may mean that some of the metal parts are rubbing against each other and need to be lubricated.  Those could be parts of the suspension, steering system and the drivetrain.  Years ago, most vehicles had to have their chassis (what you think of as the frame) regularly lubricated.  Newer vehicles are made with what some call "lifetime lubrication," but there are still parts of the chassis that need to be maintained with lubricants.  Your service advisor can help you know when that needs to be done. In your owner's manual, the vehicle's manufacturer lists components that need regular maintenance. Things like u-joints, steering joints, sway bars, bushings and joints in the suspension. Some of them may have that "lifetime lubrication," while others may not. When you bring your vehicle in for service, a technician will look for any parts that have grease fittings.  They will inspect these components ... read more

In a perfect world, all wheels and tires would be perfectly round and weigh exactly the same at every point of the wheel.  Unfortunately, they're not, and if they're out of balance, they can reduce the lifespan of your tires, make your vehicle shake like a carnival ride, and maybe even damage a few suspension parts along the way.  You don't want that! Wheel balancing, sometimes known as tire balancing, is a process by which a technician makes sure your tire/wheel assembly has evenly distributed weight.  If it isn't, it can give your ride bad vibrations.  If you feel your vehicle's steering wheel shaking, it can mean unbalanced wheels in the front. If you can feel a vibration in your seats, it could be unbalanced rear wheels. In addition to your vehicle vibrating at higher speeds, there are other signs that your wheels are out of balance. You may see uneven tread wear, or you may notice you aren't getting the kind of fuel economy you used to.  When you experienc ... read more

There's lots of good information to read in books and online.  You might not know that you can also "read" your tires and learn a lot about what shape they're in and if they are in need of attention. It's important to know how your tires are doing because a tire failure can be very dangerous to you, your passengers and others on the road near you. You read your tire by looking at the surface that rides on the road, where the tread is.  Check out the outer and inner edges.  If you notice there's more wear on the inner or outer edge than on the rest of the tread, your vehicle could be out of alignment.  Wear on an inner or outer edge could mean your wheels are leaning too much to one side.  When you see this, visit our service center soon to have the alignment checked. What about if both edges are worn? That could be a sign that you don't have enough air in that tire.  In an underinflated tire, the middle is not contacting the road surface as much as the edg ... read more

On a hot day, you want your vehicle's air conditioning to work.  When the air blowing out of your vents isn't cold, it's easy to think, "I'll just take it by the shop and have them top off my refrigerant." But while some people think air conditioning is that simple, it's actually not. If your refrigerant is low, something has to have happened for it to be depleted.  Perhaps there's a leak in the system.  Or some hoses or clamps have failed.  If the system isn't evaluated by someone who knows air conditioning, it's possible that adding refrigerant will just be a band-aid solution. It's also possible that contaminants have gotten into the refrigerant, such as carbon dioxide, nitrogen, argon, or air.  Some of those gases do not condense like refrigerant does which can increase the pressure inside the system and strain the lines and other components. At that point, the best course of action may be to have the old refrigerant (with its contaminants) bled from the sy ... read more

Ever wonder how your vehicle’s transmission is connected to your wheels? After all, when you hit a pothole or some other uneven part of a road’s surface, there has to be something that can maintain the connection between the transmission and the wheel yet keep everything moving at the same speed.  That very cool device is called a CV joint, a kind of driveshaft running to each wheel.  The CV stands for constant velocity because it keeps the drive wheels moving at a constant speed (velocity).  They’re used mostly on front-wheel drive vehicles but also in rear-wheel and all-wheel drive vehicles. The joints move up and down and adjust to bumpy surfaces.  Plus, they are covered in a rubber boot which protects them from road debris and also holds lubrication in.  There’s a CV joint and boot on the transmission side and one on the wheel side.  Unfortunately, the spot that usually fails first is that rubber protective cover (the boot).&nbs ... read more

No matter what the temperature is outside, it's important for your vehicle's engine to remain cool, calm, and collected.  Well, cool, anyway. If your vehicle has a gasoline engine, it's powered by a bunch of explosions involving spark plugs, pistons, gasoline, and air.  And the by-product of all those things working together? HEAT. There's a whole cooling system to keep everything at a tolerable temperature for your engine's parts, and a key part of that is the water pump.  Technically, it's pumping more than water. It should actually be called the "coolant" pump since the liquid that circulates through the system is a mixture of water and coolant.  Basically, the water pump keeps this coolant moving through your engine, where it picks up the engine heat, and then is pumped into the radiator where it gets rid of that heat.  When a water pump fails, the engine heat can build up.  When you get a warning light on the dash (either a gauge or a light) that show ... read more

If you've ever had a flat tire, then you know welcome it is to have a spare tire that is properly inflated, in good shape and easy to get to.  Problem is many of us don't even give our spare tire (if we even have one) a second thought. If you have an SUV or truck with a spare, it may be mounted outside the vehicle, such as on the tailgate or underneath the vehicle.  All of them, especially those underneath, take the brunt of debris, moisture, salt and dirt from the road surface, a potpourri of corrosion potential.  The hardware that holds these on can rust into a solid mess, making it hard for you or even a roadside assistance service to get off.  If you have one of those, have it checked and maintained at your vehicle repair facility on a regular basis.  They should be lubricated and cleaned periodically, and some recommend doing this service every time you have your tires rotated.  If the spare is the same size as the tires on the vehicle, it may be a go ... read more

A driver brought her vehicle into the shop the other day and told us how she was getting lousy fuel economy and that the engine was running rough.  Plus, the Check Engine light was on.  Our technician checked the code the engine had generated (why the Check Engine light was on) and found the problem.  It was a faulty Mass Air Flow sensor, MAF sensor for short. This MAF sensor is an important part of your vehicle.  What it does is calculate the amount of air going into your engine.  As you may know, air is taken into your engine where it's mixed with fuel.  Then, the spark plugs fire, that explosive fuel/air mixture detonates, and all these sequential explosions together provide the power to get your vehicle moving down the road.  It makes sense that if the MAF sensor isn't sending the engine's computers the correct information on the amount of air going in the engine, the fuel/air mixture isn't going to be right. It will either too rich (too much gaso ... read more

One of the most important things you can do to keep your vehicle running safely is to make sure your tires are properly inflated.  If one or more is vastly over- or underinflated, that has the potential to cause major handling problems and may result in a dangerous accident. All vehicles in recent years are equipped with Tire Pressure Monitoring Systems, or TPMS.  One system uses small sensors in the tires that continually check the pressure in each tire.  That sensor sends a signal to computers in your vehicle which turns on an instrument panel light warning of low pressure when at least one is very low. Or it may update a numeric reading on your instrument panel which gives you an approximation of how many PSI (pounds per square inch) of air is in each tire.  Another system works with your antilock brake system to measure the size of your vehicle’s tires.  When one wheel is going faster than another, it will spin faster. A computer sees that and alerts ... read more
