Going (Lug) Nuts (Lug Nut Replacement)

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. 

The reason that's so important is those lug nuts must be functional, especially if you find you have a flat tire somewhere on the road.  If the wheel can't come off to be swapped with a spare, it leaves few options, one of which is your vehicle may have to be towed.  All that for corroded lug nuts!

When you take your vehicle in for service, the technician who works on it keeps an eye on many things, especially if he or she is removing wheels.  It's not unusual for your service advisor to recommend you replace several lug nuts at once since some corrode at a different rate than others. Your repair facility is trying to help you avoid driving a vehicle that has wheels that can't easily be taken off when they need to be.

The good news is there are one-piece lug nuts that don't have the problem the two-piece lug nuts have, so replacing them could eliminate that from happening again any time soon.  And that's not "nuts" at all.

Fuel for Thought

If you're like most people and drive a gasoline-powered vehicle, you need to be up to speed on its fuel-related components.  They're pretty basic: the fuel, the fuel filter and the fuel pump.

The fuel's the easy part.  You probably gas up your vehicle yourself and, if you're like most drivers, price is a big factor in what you put in your vehicle. Maybe you think it doesn't matter what kind of gasoline you buy, but one major automobile association has found it does make a big difference. 

Their study showed that the additives that are put in different brands can affect your vehicle's performance.  Certain gasoline retailers sell gasoline that meets performance standards called Top Tier.  The detergents used in Top Tier gasoline help protect newer engines from carbon buildup and deposits on intake valves, all things that can affect how smoothly your engine runs, how it accelerates and what kind of fuel economy you get.  You can check online or ask your service advisor where to buy Top Tier gasoline.

Another fairly simple component is the fuel filter. Depending on the age of your vehicle, you either have a separate fuel filter or one that's part of the fuel pump.  The fuel filter keeps the crud out of your engine's fuel injectors.  You'll get a hint that your fuel filter might be clogged if you notice your vehicle won't start, your power isn't what it used to be, your fuel economy is suffering or your Check Engine light is on.

Check with your service advisor to see what your vehicle manufacturer's recommendations are on how often to service your fuel filter.  Regular maintenance can prevent expensive repairs in the future. 

Finally, the most complicated part: the fuel pump.  As you may have guessed, it is the part that gets the gasoline out of the tank and into the engine.  If the fuel pump starts to fail, it can make a clicking or whining noise when your vehicle is running.  Your engine may misfire, lose power while driving or might be hard to start in the morning.  And that Check Engine light might go on.  One thing that helps prolong the life of a fuel pump is keeping your gas tank at least a quarter-tank full at all times.  It helps lubricate and cool the pump.  If you've detected some of the symptoms of fuel pump failure, tell your service advisor.

Knowing a little about your fuel system really can be a gas!
