Differential Service at Spring Street Automotive Inc: Viva la Difference

Every vehicle on IL roads has a differential, and it is important to the proper operation of the vehicle.  But most Quincy residents don't have a clue what it is.

The differential compensates for differing wheel speeds. For example, when you turn, the inside tire on the turn travels a much shorter distance than the outside wheel. So the inside wheel of the vehicle must move at a slower speed than the outside wheel. Without a differential, the wheels would hop and scrape while turning.

Have you ever seen the large bulge in the middle of the rear axle of a truck? That's the differential. In a rear-wheel drive vehicle, the differential is located on the back axle. Four-wheel drive vehicles and SUV's have differentials on both the front and the rear axle.

You might expect that the differential is located on the front axle of a front-wheel drive vehicle. You'd be right. But the differential is called a transaxle on a front-wheel drive vehicle because its location allows it to be combined with the transmission.

In an all-wheel drive vehicle, an additional differential or transfer case is located between the front and rear axles. Differentials are strong: They have to be because of the job they do. But those tough parts need proper lubrication. You don't want your differential to seize up. That results in damage to your vehicle.

So you need to have your vehicle differential serviced regularly. It's not a complicated job. At Spring Street Automotive Inc in Quincy, we've been servicing differentials for years. The used lubricating fluid is simply drained and then replaced. Some vehicles require specific additives in the differential fluid; your Quincy service center will ensure you are getting what your vehicle needs.

The intervals in time or mileage for servicing your differential vary greatly from vehicle to vehicle. Check with your owner's manual or Spring Street Automotive Inc service advisor to find out how often your vehicle differential needs to be serviced.

The Spring Street Automotive Inc Guide to Servicing Your Differential

Differential? What's that? And what's it for? I've been told by my service advisor that I need to get it serviced, but is that on the level?

Do these questions sound familiar? They're not uncommon for Quincy drivers. A lot of us in Quincy don't know what a differential is or what it's for. Every vehicle has a differential, and, yes, it does need to be serviced. In fact, it's more important to the operation of your vehicle than the air conditioner or windshield wipers.

A differential allows your vehicle tires to move at different speeds. This happens more than you think. The best example is when a vehicle is turning. The inside wheel travels a much shorter distance than the outside wheel during a turn. This means the outside wheel has to move faster than the inside wheel. Without a differential, your tires would hop and skip while turning. They would also lose traction in sand or snow.

The location of your differential depends on what kind of vehicle you drive. On a rear-wheel drive vehicle, the differential is located in the back. For a front-wheel drive vehicle, it is located on the front, but it is usually called a transaxle. Four-wheel drive vehicles have three differentials: one on the front, one in the back and one in the middle. This center differential compensates for differences in speed between the front and rear wheels.

Your differential contains strong gears that need to be protected from dirt, debris, water and other contaminants. A differential is sometimes referred to as a “gear box.” The work of these gears is to transfer power from the vehicle drive train to the wheels.

Your differential needs fluid to lubricate and cool the gears. This fluid, even though enclosed in the “gear box,” can get dirty because the gears grind down over time, releasing tiny bits of themselves into the fluid. Also, the additives in the differential fluid break down and need to be replaced. That's why preventive maintenance for your vehicle needs to include servicing the differential.

Your owner's manual can give you recommendations on how often to service your differential. But you should also consult with your friendly and knowledgeable Spring Street Automotive Inc professional. Spring Street Automotive Inc can give you some good auto advice on whether your vehicle needs to be serviced more frequently. For example, if you drive in hot or cold IL weather conditions, your differential will need to have its fluid changed more often.

Severe conditions will also affect your vehicle care routine and your differential. Check your owner's manual for a definition of “severe service” conditions that affect your vehicle. Examples may include driving with frequent stops and starts, a lot of short trips around Quincy, hot or cold IL weather conditions and towing.

Off-roading is particularly hard on a vehicle's differential. If you are an off-roader, especially if you cross IL streams or waterways, it is important that you service your differential more frequently than the recommendations suggest.

Properly servicing your differential will extend its life and keep you out of Quincy auto repair shops. A smooth ride is the result of proper preparation and smart choices.

The Right Fluids for Your Vehicle

The current vehicles in the market have over a century of engineering behind them. They have evolved into complex and powerful machines. Developments in their engines, however, have coincided with advances in many other vehicle components, including the fluids.

It's up to people in Quincy to always use the right type of fluid for their vehicle. Your service advisor and your owner's manual are resources for auto advice on exactly what types of fluid your vehicle needs. Improper fluids can damage your vehicle and void your warranty.

Some of the fluids that have changed significantly in recent years are cooling system fluid, brake fluid, transmission fluid and motor oil. Each of these comes in many varieties now, and it's hard to know exactly which one your vehicle needs.

Cooling systems were once made of iron, steel and rubber. One coolant could be used to protect all of these materials. But new cooling systems have components made from a variety of metal alloys and several kinds of plastic, and coolants now contain additives that protect these various materials from corrosion. Since the materials vary among manufacturers, they require different additives, which means there are now several coolants on the market. The type of coolant your vehicle needs depends on the materials used in its cooling system.

Most vehicles used to require DOT 3 brake fluid. But now many vehicles need DOT 4 or DOT 5. Some Quincy drivers mistakenly think the higher numbers reflect an increase in grade—that DOT 4 is somehow better than DOT 3. But the truth is, the numbers represent variations in formulation. The different formulas have evolved to meet the demands of newer and better brake systems. For a long time, transmission fluid came in two varieties: regular and friction-modified. But transmissions have come a long way recently and so have the fluids that protect and lubricate them. There are several new types of fluid on the market, but your vehicle is designed for just one of them.

Of all the automotive fluids, motor oils have experienced perhaps the greatest advances in engineering and technology. A number of new weights and formulations have recently been developed to meet the needs of modern engines, which have more parts and tighter tolerances than ever before. Engines have become more sophisticated and complicated, but they have also increased in power and fuel efficiency. Despite these changes, Quincy vehicles still need them to be highly durable.

That's the job of motor oil. Motor oil still has to perform its original function—lubricating and protecting the engine. It is formulated to help clean the engine as well. Modern motor oil also has to be thin enough to penetrate small engine passages yet still be resistant to vaporization.

Specialized motor oils have also been developed for high-mileage vehicles. If your vehicle has 75,000 miles/120,000 km or more on it, you might consider switching to one of these motor oils. They contain extra detergents that help clean older engines, additives that condition seals and gaskets that can become brittle with age. High-mileage motor oils come in weights and types just like regular motor oils, and Quincy drivers should match the proper weight and type of high-mileage oil to their vehicle in the same way you would regular motor oil.

Over time, vehicles have developed in complexity and variety, and their fluids have developed as well. Each vehicle is matched to a set of fluids that meet its specific requirements. IL vehicle owners should take care to learn their vehicle's fluid requirements before topping off at home. A large part of preventive maintenance for Quincy drivers is making sure your vehicle's fluids are clean and adequate, but they must be the proper type as well. As our vehicles become more sophisticated, car care becomes more sophisticated as well.

Learning about proper fluids for your vehicle will help you maintain its performance and prolong its life. Talk to us at Spring Street Automotive Inc in Quincy.

Suspension Service at Spring Street Automotive Inc in Quincy

During an inspection at Spring Street Automotive Inc in Quincy, your friendly and knowledgeable automotive service technician will check for worn, broken or missing parts.

Here's a quick rundown of suspension system components:

There are the springs which hold the weight of your vehicle. There are several varieties of springs. Springs are heavy duty parts that rarely break or wear out. Shock absorbers work in conjunction with springs to smooth out the ride and help keep the tires on the road. Good shocks are essential for handling performance and ride comfort.

You've probably heard of struts. They combine a shock absorber and a coil spring in one unit. Shocks and struts will wear out over time. If your tires develop a cupped wear pattern, your shocks or struts may be wearing out. This is from the shocks bouncing unevenly. You may notice a floaty or drifting sensation when cornering. If the front of your vehicle dives excessively when stopping, or rocks back and forth after you've stopped, your shocks may be worn out. And if they are leaking fluid, it's definitely time to replace them at Spring Street Automotive Inc.

If you are experiencing any of these symptoms, visit Spring Street Automotive Inc for a suspension inspection. Same applies if you've been in an accident that involved one of your wheels. If your vehicle suspension actually fails, it could lead to a serious accident, so don't put it off.

When you replace your shocks, it's usually a good idea to replace all four at the same time. That'll give you more even handling. Talk with your friendly and knowledgeable pros at Spring Street Automotive Inc because you don't want a big difference between the performance of your shocks from wheel to wheel, and replacing all may be the safest bet.

There are different grades of shocks and struts. You always want to use a replacement shock or strut that equals the one that came as original equipment when your vehicle was new. But remember, they were designed to meet the expected needs of the broad range of Quincy people who buy that particular vehicle. Your needs may be more specialized.

For example, if you want increased handling performance, your Spring Street Automotive Inc service advisor can recommend an upgraded shock or strut specially designed for improved handling. If you haul heavy loads or trailers in Quincy, we can recommend some heavy duty shock absorbers.

When "Shady" is a Good Thing

Just like your skin can burn from too much sun, so can the paint on your vehicle.  It can turn dull, oxidize and fade the more ultraviolet rays beat down on it. One solution is to park in a shady spot, or you can buy a cover for your vehicle and put it on when you know it's going to be sitting in the sun for awhile. Yes, it takes a couple of minutes to put on, but in the end, keeping the gloss on your paint will help it retain its beauty… and its value.

And it's not just the sun that can damage your vehicle's paint.  Grit, bird droppings, sap, dust and dead bugs can all ruin the paint.  So, keep your vehicle clean.  Wash it with a soap made especially for vehicles. Dry it with special towels that won't scratch your paint.  Remember:  DON'T WASH YOUR VEHICLE IN THE SUN. Once your vehicle is washed, protect the paint even further with a coat of wax.  DON'T WAX YOUR VEHICLE IN THE SUN, EITHER.

Don't forget the vehicle's interior.  Plastic components inside can literally disintegrate when sunshine heats them up.  That's what causes that oily film on the inside of the windows. So, pick up some of those reflective panels that unfold, placing them in the windshield and back window when you know the sun and heat are going to be intense.  They'll keep out the ultraviolet light and help the interior stay cooler as well.  That will help prevent upholstery from fading and plastic from cracking.

While you're at it, keep your interior's interior clean, too.  That dust and dirt can literally bake into the dashboard, the seats, console and carpeting.  There are cleaning products designed to clean your vehicle's interior that won't stain it or dry it out.

You invested a lot of money into that vehicle.  The sun and dirt are just waiting to destroy it.  Defend your valuable vehicle against the elements.  Hey, it may not wind up on display in a museum, but it'll look great and last longer with just a little TLC.
