When you feel your vehicle vibrating as you're driving down the road, one cause could be something you may not have ever seen: your driveshaft. It is underneath the vehicle and most drivers don't climb under there to take a look very often. The driveshaft is a cylindrical part that helps conduct the rotational power from your engine to your drive wheels. If you have a four-wheel drive vehicle, you may have two driveshafts. The drive shaft has bushings, and when they wear out, that's a likely source of the vibrations. When the bushings are in good condition, they prevent the driveshaft from vibrating. And if you don't get your vehicle repaired fairly soon after discovering vibrations, they'll continue to get worse and cause other components of the drivetrain to wear out. The driveshaft is, of course, only one part of the drivetrain. It includes other parts such as axles, transmission, differentials and joints. They all work together and ne ... read more

Engines required a lot more maintenance in earlier times. You'd have to have your spark plugs, wires, rotors, caps, distributor points, fuel and air filters changed periodically. There were mechanical adjustments of a vehicle's timing, dwell, spark gap and idle mixture, too. Unless you like to tinker with old cars, a lot of those terms won't mean much to you. That service was called a "tune up" back then, and you can see why. But now, computers have reduced the number of maintenance items, and a tune up is a whole lot different than it used to be. In fact, in some vehicle service facilities, that term is also a thing of the past. A tune up of today would more accurately be called simply periodic maintenance. Now, most vehicles still have spark plugs and wires, fuel filters, air filters and PCV valves, and they should be inspected tested and/or replaced at regular intervals. Your vehicle's manufacturer has made recommendations on how often that ... read more
