In That Case? (Transfer Case Exchange)

Ever wonder how all-wheel-drive or 4-wheel-drive vehicles get the power from the engine to the front and rear wheels? The magic happens in what's called a transfer case.  In some all-wheel-drive vehicles, it's sometime called a power take-off unit, or PTU.

Inside the transfer case is a set of gears.  And to keep those gears meshing smoothly, they have to be lubricated and kept cool.  What does that is called transfer case fluid. Depending on your vehicle's type of transfer case, it is filled with either an automatic transmission fluid, a gear oil that's a bit thicker or transfer case fluid designed to be use for your transfer case.

As happens with all lubricating fluids, the transfer case fluid has things in it that break down the older they get.  They have corrosion inhibitors, detergents and anti-foaming agents that keep the lubricant from getting air bubbles in it. Transfer cases don't have filters in them to clean out impurities.

If you don't have your transfer case fluid exchanged for fresh, you risk damage to the case, and that can run into thousands of dollars.  So the wise driver makes sure the fluid is changed according to the manufacturer's recommendations.  For many vehicles, that is every 30,000 mi/50,000 km, but some require it more frequently.   Your vehicle service facility can advise you on what your vehicle's optimal interval is.

During the fluid exchange, any metal filings that may have come off are cleaned off of the drain and fill plugs that are usually magnetized to catch the stray metal pieces.

If you hear grinding noises coming from under your vehicle or if it is having trouble shifting gears or going in and out of 4-wheel-drive, those could be signs your transfer case needs service. In that case, have our technicians check it out.  The best plan of action?  Keep your transfer case fluid maintained and it should keep you heading down the road for years to come.

Rubber Match (Tire Replacement)

A set of new tires isn't probably high on anyone's list of exciting purchases.  But since your life is literally riding on them, it's probably a good idea to know when it's time for you to buy new ones.

If you've been feeling your vehicle slipping more in wet weather or it takes a longer distance to stop, those are a couple of signs you may need new rubber all around. Here's how to make your decision.

First thing to do is look at your tires.  The surface of the tire that contacts the road is the tread. When that tire was new, the tread was deep (the grooves in the rubber that provide traction). If they're starting to look somewhat smooth, you have a seriously worn tire that definitely needs replacing.  Bring your vehicle in for us to look at your tires and we can check your tread with a tread gauge.

Also look at the sides of your tires.  If they have cuts or cracks in them, or if you see signs of bulges or scrapes made by hitting curbs or potholes, those could be signs of serious damage. 

Keep an eye on your tire pressure monitors.  If you notice one or more of your tires showing frequent pressure changes, that needs to be checked out. 

One other thing you probably didn't know is that your tires all have birthdays, and they're printed on each sidewall.  When you bring your vehicle in for us to inspect your tires, we can tell you how old they are. That's important because rubber deteriorates with age, even if they don’t have that many miles on them.  Tire manufacturers recommend replacing tires when they reach a certain age, usually from six to ten years old. 

Now the question is, which tires should you buy? That's one for your service adviser who can recommend replacements based on your driving style, the model of vehicle you own, where you drive most often, and other factors. 

Oh, and if you want your new set of tires to last as long as possible, remember to have them rotated regularly, keep the right pressure, and don't drive aggressively.

A Clean Sweep (Fuel Injector Cleaning)

Your vehicle gets its power from burning fuel, usually gasoline, and it counts on something called fuel injectors to send gas to the engine in a spray that is easy to ignite.  It’s a precise operation, and when it’s working well, you have plenty of power and an efficient engine.

But after time, contaminants in the fuel system may prevent the injectors from spraying like they’re supposed to.  They can also shoot contaminants into the engine. 

One sign that could point to dirty fuel injectors is a misfiring engine. Misfires can be caused by several things, so it’s a good idea to bring your vehicle to us so we can trace the cause. Another sign is that your fuel economy has gone downhill or your engine doesn’t have the “pep” it used to.

If we discover that your injectors are clogged or not working the way they should, we can clean them to get rid of those contaminants to restore your engine to its top performance.  When you bring your vehicle to us, we will connect the flushing equipment, flush out the injectors and reassemble the system.

A good time to have fuel injectors inspected is when you bring your vehicle in for routine maintenance.  An oil change is an ideal time to have a technician take a close look at your entire fuel delivery system. 

When you have your fuel injectors cleaned, you may see your mileage go up, your engine performance improve, and your exhaust emissions decrease.

Restore Your Get-Up-and-Go (Fuel and Air Induction Cleaning)

You may have heard the old saying, "My get-up-and-go got up and went." If your vehicle's engine's fuel economy is noticeably worse, your engine is idling roughly or stalling or your vehicle's acceleration isn't what it used to be, ask your service advisor if you might need your vehicle's fuel and air induction systems cleaned.

As the hours pile up on your engine, carbon deposits can build up.  It's not unusual for some of the impurities and additives in fuel to leave behind a black residue that eventually will negatively affect your fuel economy and performance. Maybe you're noticing your engine is harder to start, you hear knocking or pinging in your engine and your vehicle just doesn't have the pep it used to.

While it's a sophisticated process with a lot of components, a gasoline engine essentially produces power by drawing in air from the outside and mixing it with fuel in the cylinders where this blend of fuel and air is ignited by spark plugs in synchronized explosions.

The fuel and air enter your engine through the fuel induction system and air induction system. Because of things like high operating temperatures and impurities, carbon in the fuel can leave behind dark, sooty deposits in the fuel induction system such as the fuel injectors and the throttle body. These and other residue reduce your engine's efficiency and performance. Our service center can use special fuel injector cleaners to remove those deposits from your engine.

The technician may manually clean some of the deposits and also put a fuel additive in the fuel tank that will get rid of other deposits that are still in the fuel system

Keeping the air induction system clean is also important.  A technician can use a liquid cleaner specially designed for the job. Not only can this improve your fuel economy, it may also reduce exhaust emissions and help your engine last longer.

Most gasoline now contains detergents that help reduce or prevent these problems, but direct injection is now being used in more vehicles that are more susceptible to clogging. Ask your service advisor if your vehicle could benefit from fuel and air induction cleaning.

Light Up your Life (Headlamp Replacement)

Did you know that having a burned out headlight can result in your rearview mirror reflecting some flashing lights? In other words, you might get pulled over by the police for only having one working headlight, because in most places it's against the law. 

Not only is it illegal to drive with one headlight burned out, but it's also dangerous. You can't see down the road nearly as well at night with only one headlight, and other drivers can't see you as easily either.

The good news is many newer vehicles warn you when one of your headlamps burns out. When that happens, have it taken care of as soon as you can.  While there was a time when all headlamps were pretty much the same, the same isn't true these days. There are halogen, Xenon, LED and other technologies used in modern vehicles.  Plus there are sealed beams (like those on older vehicles) and capsules.

If you have a burned out headlamp, ask your service advisor for recommendations.  Usually when one side goes, the other isn’t far behind. Many suggest replacing both headlamps at the same time.  Your vehicle's owner's manual can tell you what the manufacturer recommends.  You also can ask your service advisor about upgrading to a headlight that might give you better visibility. 

In order to make sure you're able to see down the road the way your vehicle was designed and not blind oncoming drivers, it's vital that new headlights be aimed properly.  That's another good reason to have this service performed by a technician. Now, that's a really bright idea.
