If you hear a squealing noise when you turn your vehicle, it's trying to tell you something is wrong. After all, it never made that noise before, right? The sound you hear may becoming from a few sources. Let's take a look (or a listen) to some of the possibilities. First, you almost certainly have power steering in your vehicle. Without power steering, you practically have to have arms like Arnold Schwarzenegger to turn, so automakers have technology to assist your steering, either mechanically or electrically. For a long time, the most common power steering has been hydraulic, using a belt to supply power from the engine that turns a power steering pump full of a fluid that helps you steer. Sometimes that fluid gets low because of a leak or some other problem. The belt could wear out and start squeaking, and you might feel the steering start to become harder. Your service repair facility can figure out the problem and offer some solutio ... read more

If you've ever walked into your garage and noticed it smelled like gasoline, pay attention. Gasoline can be dangerous, both from the health problems fumes can cause and the fire danger gasoline presents. There are many things that can cause a vehicle to give off a gasoline odor. One of the easiest to track down is the gas cap. It could be missing or it doesn't seal well any more (they do wear out). That can also cause the Check Engine light to light up, so those are clues to tell your service advisor when you take it in for diagnosis. Another thing that can cause the Check Engine light to come on and produce a gasoline smell is the fuel filler neck. It's the part that goes from the place you put your fuel in to the gas tank. Over time, these can wear out and fail (they're made out of rubber or metal). They can leak gasoline, too. It's always a good idea to check the garage floor for any gasoline puddles. Note the location of the puddle in relation to ... read more

You've probably never paid much attention to the writing on the sides of your tires, but they contain a wealth of information. There's a long combination of letters and numbers that can tell you a whole lot about what tires your vehicle was designed to be riding on. Let's check out this example found on an SUV: P245/70R17 108T. The first letter, P, means it's intended for passenger vehicles. If there's no letter, it means it's a metric tire. If there's an LT at the beginning or end that means a tire designed for light trucks. Moving on to our example, the 245 shows how wide the tire is in millimeters from sidewall to sidewall. The number that follows in our example, 70, means the height of the tire is 70% of its width. The letter after that in our example, R, describes the type of tire (on this vehicle, radial). Following that is the diameter in inches, in our SUV example, 17 inches. How much load the tires' sidewalls are designed to take ... read more

There are some boots that don't come in a shoe box and aren't worn on your feet. They are called axle or CV boots, and they can be important parts for many vehicles. That CV stands for constant velocity. CV axles are mainly used in front-wheel drive and all-wheel drive vehicles. They're also used in some rear-wheel drive vehicles with independent suspensions. They have two CV joints, one inner and one outer, placed between the axle and the drive wheels. That way the vehicle's engine power can drive the wheels, no matter what angle they are. They also adjust for the different speeds wheels turn as they go around corners. Because roads are full of all sorts of hazards (dirt, oil, water, grime), these CV joints need to be protected. They also have grease in them to keep the bearings moving smoothly. That's the job of the rubber boots that are supposed to keep that debris out. These CV or axle boots are made of rubber or plastic and usu ... read more
