Here's a part of your vehicle you probably don't think about much: lug nuts.  They're what fasten your wheels onto your axles.  Pretty important, right? In order to take the wheels off your vehicle to service the brakes, rotate the tires, etc., the lug nuts have to be in good shape so a wrench will grip them tightly.  Because lug nuts are on your wheels, they are exposed to all the elements of the road (salt, water, grime) and really take a beating. Unfortunately, some manufacturers have made them out of two different metals.  Underneath is the working part of the lug nut, made of steel.  On top is the decorative (the "good looking") part, made out of chrome, stainless steel or aluminum.  After a while, the steel part begins to corrode and expands.  That changes the shape of the outer cap, sometimes rounding off the hexagonal edges and making it hard (if not impossible) to either loosen or tighten the lug nuts since the wrench won't fit any more.  ... read more

Sometimes the movie is better than the book, sometimes it's the other way around.  But when it comes to your vehicle, the best book of all is the owner's manual. The plot is simple: Owner wants long life and dependable performance from the vehicle, manual has the way to achieve that long life and dependable performance. And yet, it's amazing that some people will own a vehicle for years and never even crack this book.  They'll only read it when they absolutely have to, for things like finding out how to change the clock.  Ok, so you're probably not going to rush right over to your glove box and start reading the owner's manual cover to cover.  We know that.  But just think of what you can get out of it. Consider this.  Those who wrote or helped write this book include the engineers who designed it and the people who tested and refined it.  They know more about your vehicle than anyone, period.  They know how long a part is likely to last and what ... read more

We've all seen drivers who do things that—let's be frank—really irritate us.  They're inconsiderate, can put people in danger and make the road a much less friendly place.  They really "T" us off.  These are the bad drivers who fit their description to a "T."  The Tailgater.  You've seen this terrible driver who follows a few inches off the bumper of the vehicle ahead.  We all know what's going to happen if the driver ahead of the tailgater has to slam on the brakes.  And we've all been that driver followed by the tailgater, whose vehicle fills up your entire rearview mirror.  The tailgater is likely not in a great frame of mind and, thanks to his or her stupid driving practices, the "tailgatee" is getting pretty ticked off as well.  That's a formula for a big problem. Know anybody who respects or likes a tailgater? Didn't think so The Texter. All sorts of people think they are perfectly capable of texting while driving.  I ... read more

Who thinks about their fuel gauge?  You probably don't… until it doesn't work any more.  Then you have to guess how much fuel is in your tank, and that's no way to live life on the road.  Fuel gauges, like every other part in your vehicle, can fail.  And when yours stops working, you will probably want to head over to your service facility soon, because no one relishes running out of fuel. The fuel gauge system is much more than just the gauge you can see on your instrument panel. Most systems have a float inside the fuel tank that goes up and down depending on the fuel level.  It's called the fuel sending unit, and it sends an electrical signal to the gauge (on the dash) telling it to display how much fuel is left in the tank.  So, what could go wrong?  Well, a few things.  For one thing, corrosion from bad fuel can cause it to stick and it won't move up and down any more.  So you could fill up your tank and the gauge would still rea ... read more
