Some vehicles come with either "all-wheel drive" (AWD) or "four-wheel drive" (4WD), and you may have wondered if there's any real difference between those terms. Cars only have four wheels, after all, so when "all" of them are doing the driving, that's four-wheel drive - isn't it? The logic makes sense, but AWD and 4WD have actually evolved into technical terms that refer to distinct mechanical systems. Whether you're shopping for a car or yours needs repairs, you'll want to take an educated approach, so let's walk through the ins and outs of each system.
Sluggish. Squealing. Unreliable. Vibrating. If any of these descriptors fit your vehicle’s recent behavior, it just might be trying to tell you something – like it’s time for a tune-up.
Today’s vehicles differ significantly from their decades-old brethren that required a tune-up every 10,000 or 20,000 miles. With newer vehicles, it’s increasingly common for manufacturer-recommended service intervals to stretch to 100,000 miles before certain maintenance items, such as replacing the spark plugs, should be completed.
Cold weather and vehicle performance aren’t necessarily the best of friends. “Every mile is two in winter.” That quote is attributed to the English poet George Herbert. Even though he wasn’t referring to driving an SUV with heated leather seats, his philosophy still applies today. Winters can be hard, cold, long, and dark.
You may be surprised – shocked, even – to learn just how important automotive shocks and struts really are. If you need new shocks or struts, don't delay, because these are crucial safety items that help you maintain control behind the wheel.
But wait a minute. How do you know whether or not you need replacements? And what does a shock or strut even do in the first place? Every driver should know the answers to these questions, yet few actually do. So we're going to walk you through the answers, step by step.
It's Time for the 21st Century Tune-up Times are changing...cars are changing. One of the biggest changes in today's automotive industry is the perception of a "tune-up." Ask 10 vehicle owners their definition of a tune-up and chances are there will be 10 different answers. The classic "tune-up" was once the heart of the automotive business and contrary to some beliefs; today's modern vehicles still need tune-ups to keep them performing at the most efficient levels.
Often confused with wheel alignment, a properly balanced wheel is a beautiful, perfectly tuned wheel-tire combination. This is accomplished by placing measured lead weights on the opposite side of the "heavy spot"—the noticeable tread wear on your unbalanced tire.
