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.
That's the same thing that's happening with an out-of-balance tire/wheel combination. A technician has special equipment to figure out where to put small weights on the wheel to get things back in balance again. But it could be that you hit a pothole some time ago and bent the rim. Or your tire isn't as round and even as it once was. That could be due to age, damage or wear and tear. The technician will know and offer you options.
Another possibility for that vibrating wheel is a faulty brake, such as warped rotors or a sticky caliper. All of these issues can be evaluated as part of regular, routine maintenance with us. There are many things that cause vibrations in your wheels. But you don't want any bad vibes when it comes to your vehicle.
