When you're driving and turn a corner, you probably aren't aware of all that's going on with your wheels.  The outside wheels have a longer distance to travel than the inside wheels, so there are gears that allow the wheels to go at different speeds when you turn.  That set of gears is called a differential.  In front-wheel drive vehicles, it's by the transmission and called a transaxle.  Rear-wheel drive vehicles have the differential, naturally, on the rear axle. Many all-wheel and four-wheel drives add a center differential since power has to go to the front and rear wheels. (Some newer vehicles power wheels with electric motors, but that's a whole different story.) Time and distance traveled eventually can take their toll on the differential, and you may notice some noises you hadn't heard when your vehicle was newer.  Sometimes you'll hear a whir that might change in pitch when you turn.  You may hear clicking sounds when you're moving.  Others d ... read more

No one likes to be greeted in the morning by having someone screech at you.  The same goes for a loud, high-pitched noise your vehicle greets you with every time you start the engine.  If you're wondering if that's normal, no, it isn't.  And it is worth getting checked out.  The good news is that it might be nothing serious.  Then again, it may be. The first things to suspect any time you hear a high-pitched sound coming from the engine are belts.  They have tension on them and they're trying to turn lots of different pulleys, pumps and other equipment the engine needs to work properly.  The noise could come from the belts starting to wear out and dry out. If one of those belts breaks at an inopportune time, not only can it strand you somewhere, the damage to the engine could be very expensive to fix. Other things that will cause a high-pitched sound are the pulleys and tensioners.  The tensioners keep the right amount of pressure on the belts an ... read more

Warm weather can bring severe storms, and when the rain is coming down hard, that's one time you really need to be able to see as clearly as possible out your windshield.  Having wiper blades that are fit for the job are important to maintain that safe view. Maybe you live in a climate where you use blades made for winter weather and you have haven't changed them since the weather changed.  Those blades are made of heavier materials and don't work as well in warmer temperatures. Blades made for warm temperatures are lighter and clear water better in the warmer months. The general rule of thumb is you should change your blades every six months, but if you use them a lot, you might have to change them more often.  A couple of signs that your blades need changing? If you are seeing streaks on the glass or hearing a chattering sound when your wipers are working, time for a new pair. Wiper blades have cleaning windshields on vehicles for more than 100 years.  The origina ... read more

Heat isn't easy on vehicle tires, and as the seasons change, make sure yours are ready to take the heat.  Let's talk first about inflation.  Heat causes air to expand, so heat alone can raise the pressure in your tires.  If you are driving on overinflated tires, they won't have as much contact with the road surface.  In that case, it will take you a longer distance to stop. On the other hand, you don't want your tires to be underinflated during hot weather, either.  That can cause your sidewalls to flex.  Friction will then hike up the temperature and your tire can be in danger of blowing from the added heat. Other things can cause problems, such as uneven wearing.  Your service advisor knows the signs to look for and can diagnose where the wear is and what is likely causing it.  Another thing a technician will look for on tires is tread depth and the condition of the sidewalls.  Any cuts, cracks or bulges could be indications that your tire ... read more

Nearly every modern vehicle on the road today has power steering, a wonderful invention that makes steering take far less effort than it did in the "good old days."  Today, we take our steering for granted: until something goes wrong, that is. Most power steering these days is rack-and-pinion, the rack being a metal bar between the front wheels with notches in it and the pinion being a gear whose teeth fits into those notches.  Adding power assist makes it easy to turn. That assist comes in the form of hydraulic fluid that is pressurized by a pump powered by the engine, an electric motor that adds a power assist or a system that uses both an electric motor and hydraulic fluid. Your vehicle usually gives you a heads up that something is going wrong with its steering. Here are a few signs to look for: A humming, whirring, rubbing or grinding sound coming from you engine compartment when you turn. Signs of hydraulic fluid leaking, such as wet spots under your vehicle. The smell ... read more

Keeping your vehicle's brakes in top shape is one of the most important things you can do for your safety and those on the road with you. Most drivers know a little about brake pads and rotors but maybe not so much about another brake component called the calipers. Disc brakes work by a mechanical system that presses your brake pads against discs called rotors (you can usually see these discs through your wheels). The friction stops your vehicle smoothly when everything is working the way it should.  The calipers use the hydraulic pressure of the brake fluid to apply the stopping power.  After they've been on your vehicle for a while, the calipers can get stuck or wear out.  If calipers on one side of the vehicle work correctly and not on the other, you might feel a pull in one direction.  You might feel the same kind of pull if the caliper is stuck and is applying constant pressure.  You might hear scraping or squealing coming from a stuck caliper and you migh ... read more

So winter has arrived and you don't feel confident in how your 2-wheel drive vehicle does in the snow and ice.  You envy all those people with all-wheel-drive (AWD) and 4-wheel-drive (4WD) cars, trucks and SUVs.  You start thinking, "I need one of those.  I'll be able to go anywhere without any worries."  The truth is there might be another option for you that you might not have thought of.  Sure, you've seen the ads that tout the advantages of AWD and 4WD, and some of the videos make it look like they can handle everything Mother Nature can throw their way.  The truth, though, is that vehicles with drive wheels at all four corners can't stop any more quickly than those with 2-wheel-drive.  Yes, AWD and 4WD vehicle have advantages when it comes to acceleration, but when it comes to stopping and handling, they generally don't.  If you buy a new AWD or 4WD vehicle, you are going to spend thousands of dollars.  Maintenance and upkeep costs are ... read more

Your vehicle's brakes wear out.  It's inevitable. You'll notice it when you step on the brake pedal and feel it harder to stop, or there's vibration when you are braking.  Most modern vehicles have disc brakes that each use a brake pad that press on a disc (disc brakes!) called a rotor.  The friction between them enables you to stop, and each time you do a little bit of the pad and the rotor wears down. The original brakes on vehicles used a rotor that was thick enough to last through at least two replacements of the pads.  But vehicle manufacturers who want to save costs and weight now make them thinner, and sometimes the rotors have to be replaced after the first pad replacement.  But not always. Vehicle manufacturers specify a minimum thickness to provide safe braking.  Sometimes rather than having to have your rotors replaced, they can be put on a lathe and resurfaced.  In other words, the surfaces of the disc can be slightly shaved off so the sur ... read more

Did you know that having a burned out headlight can result in your rearview mirror reflecting some flashing lights? In other words, you might get pulled over by the police for only having one working headlight, because in most places it's against the law.  Not only is it illegal to drive with one headlight burned out, but it's also dangerous. You can't see down the road nearly as well at night with only one headlight, and other drivers can't see you as easily either. The good news is many newer vehicles warn you when one of your headlamps burns out. When that happens, have it taken care of as soon as you can.  While there was a time when all headlamps were pretty much the same, the same isn't true these days. There are halogen, Xenon, LED and other technologies used in modern vehicles.  Plus there are sealed beams (like those on older vehicles) and capsules. If you have a burned out headlamp, ask your service advisor for recommendations.  Usually when one side goes ... read more

There's nothing that radiates cool like a vehicle radiator that's helping to keep your engine running at the proper temperature.  You don't have to baby it, but you can't simply ignore it, either.  Let's take a quick dive under the hood to let you know what the radiator is doing.  It takes the heat your engine produces and moves that heat outside.  It's not an easy job and heat is an engine's number one enemy.  Now that you're thinking how nice you want to be to your radiator, we have a couple of ideas how you can take care of it. The easiest thing is to pay attention to your vehicle's temperature gauge. If it gets in the "too hot" or "not hot enough" range, have it checked out soon.  Make sure your coolant is kept at the correct level and if you see a trend that you have to add coolant more than a couple of times a year, you might have a leak. Even if there are no obvious problems, every couple of years or so, consider taking your vehicle in for radiator ... read more
