Your vehicle has a way of letting you know when something's wrong. Consider a vibrating steering wheel. It certainly didn't do that when it was new, so that shake is trying to tell you something. There are a few things that can cause your steering wheel to vibrate as you drive down the road. One of the most common is out-of-balance tires. You may not only feel that wobble in your steering wheel, you might also feel it in the tires. Sometimes it's not there when you're driving at lower speeds through residential areas, and sometimes it starts when you hit highway speeds. So what is tire balance anyway? Well, you have a rubber tire that fits around a metal wheel. It should have the same weight all the way around. If it doesn't, it will start getting the shakes. Ever load your washing machine so that all the clothes are at one side of that drum that spins? When it hits the spin cycle, it can throw that washer against the wall. Th ... read more

What part of your vehicle has little metal balls inside that are lubricated and allow you to cruise on down the road? They are wheel bearings, and automotive designers might argue they are human beings' second greatest invention of all time (the first is, of course, the wheel!). You have a wheel bearing at each wheel. They allow your wheels to turn freely, minimizing friction that would ordinarily slow you down when metal meets metal. When one of your wheel bearings starts to go bad, it lets you know. A wheel bearing does its work quietly when it's in good health but starts getting noisy when it isn't. People describe the noise differently. Sometimes it sounds like road noise, a pulsating, rhythmic, sound. That pulse speeds up when your vehicle speeds up. Here's what's happening when you hear that sound. As mentioned, the bearing has these little metal balls inside a ring. They have a lubricant inside to reduce friction between the ... read more
