When Do My Shocks Need to Be Replaced?

A good suspension system gives a vehicle a smooth, even ride while providing Charleston drivers with good handling and control. But like any system on your vehicle, parts of the suspension system can wear out, leading to a lower ride quality and safety concerns. So it's a good idea for drivers in Charleston to remember their suspension system in their schedule of preventive maintenance. Springs do most of the work of the suspension system. The most common types of springs are coil and leaf, but air springs and torsion bars are becoming more common. The body of the vehicle is “suspended” by the springs.

If springs were the only working component in your suspension system, however, you'd spend your travel time bouncing up and down like a bobblehead. That's where your shocks come in. They keep the rebound, or bounciness, of the springs under control. Shocks also keep your tires on the road, which keeps the driver in control of the vehicle. Some vehicles have struts in their suspension system. Struts are a compact combination of springs and shocks. They do the same job but in a single package.

Shocks wear out gradually, so it can be difficult for Charleston drivers to notice when they need to be replaced. There's no definitive point when a vehicle's ride goes from "smooth and controlled" to "a bit imprecise." To check if your shocks or struts are worn, you should first do a visual inspection on them. If they are leaking fluid, they need to be replaced.

There are other less obvious signs that your suspension system needs attention. For example, an uneven, cupping wear on your tires may indicate that your shocks are worn. If your vehicle feels “floaty” when you turn, or, in other words, you don't feel that you have full control of the vehicle, you should check your shocks. Also, if the front end of your vehicle dips noticeably when you stop, it's time for new shocks.

Your owner's manual gives recommendations on how often the shocks should be checked, usually between 15,000 and 30,000 miles (24,000-50,000 km). If one of your shocks does need to be replaced, you should replace all four. This will keep your suspension even and ensure good handling of your vehicle. If you carry heavy loads, tow a trailer or drive on uneven Charleston area terrain, you might also consider upgrading to a heavy-duty shock.

Regular shocks contain hydraulic fluid. The fluid helps them absorb the bumps or “shocks” of the road so the impact doesn't transfer to the vehicle's body. Premium shocks are filled with compressed nitrogen gas, which costs more but does a better job of controlling body motions. Regular shocks can develop air bubbles that reduce their effectiveness; the premium shocks don't have this problem. So if you want higher handling performance, if you drive off-road around WV or if you just want added comfort, you should consider upgrading to premium shocks or struts.

Replacing struts can put your vehicle out of alignment, so an alignment check should always follow this type of repair. Talk to your service advisor at Steve & Stacy's Servicenter in Charleston for more information.

Tracking True in Charleston: Wheel Alignment

At Steve & Stacy's Servicenter, we occasionally see severe tire damage that could have been prevented with proper wheel alignment. During a Steve & Stacy's Servicenter alignment service, your vehicle is put on an alignment rack where the tires, steering and suspension parts are inspected for problems. Then the alignment is charted and checked against the vehicle factory settings. Adjustments are made to bring the wheels back into alignment. This gets all four wheels moving in precisely the same direction.

If you don't remember hitting a pothole, how do you know if your wheels are out? The most obvious sign is that your vehicle pulls to one side. Also, your steering wheel may not be centered when you're going straight. If you're in the habit of checking your tire wear regularly, you may notice the edges of one or more tires rapidly wearing down. You should have your Charleston auto service center look it over. Of course, if you've been in an accident, you should get your alignment checked.

It's not surprising that a forceful impact can seriously knock tires out, but remember that a series of smaller ones can add up. That's why your vehicle manufacturer recommends periodic alignment checks. If your vehicle owner's manual doesn't advise a specific interval, once a year might be appropriate. Check with your Steve & Stacy's Servicenter service advisor. As with most other preventive maintenance services, the cost of the alignment is a heck of a lot cheaper than having to purchase new tires earlier than expected.

Economics of Maintenance for Charleston Auto Owners

Buying a new car in Charleston is always a big financial decision. The allure of that new car smell is powerful, to be sure. But what if your current car is still in good shape? How do you decide?

People in Charleston who've been used to driving a new car every three to five years may be having second thoughts in this economy. For many, the question is, how does the certainty of a new car payment stack up against uncertain repairs for a car that may be out of warranty?

For purposes of our discussion, let's assume you live right here in Charleston and have a five year old vehicle. It's now paid off. If you keep it, you fear that there'll be some repairs over the next five years, but you really don't know what to expect. For help we turned to maintenance and repair information for cars and trucks. With this data, they project likely service and repair costs for a particular make and model. They're able to use manufacturer's maintenance schedules and repair histories for the projections.

Of course, these projections can't predict what will happen to your vehicle in Charleston, but they do give you information to use in your decision.

Let's look at the numbers for a five year old Toyota Camry V-6. In this example, the combined maintenance and repairs for the five year period is $5,748. This works out to an average of $96 a month. The year-by-year averages range from a low of $49 a month to $124 a month.

So compare $96 a month with a new car payment. And it's actually better news than that; you would still have maintenance expenses with a new car, so the repair element could be less than half that figure.

Here are numbers for some other five year old vehicles from around Charleston:

• Ford Escape - $116 a month
• Chevy Silverado - $131 a month
• Jeep Grand Cherokee - $138 a month
• Hyundai Accent - $85 a month.

Now, if your vehicle is older than five years, have a chat with your Charleston service advisor at Steve & Stacy's Servicenter. We see hundreds of vehicles through our bays every month and we know your car. See if there's any particular problem in common with your vehicle that you might see over the next couple of years.

And of course, the best way to keep future repair costs down is to take care of all your scheduled maintenance. This is especially important in older vehicles that have had time to accumulate some deposits.

There are special motor oil formulations that help clean older engines and protect and recondition their seals and gaskets.

We hope this eliminates some of the unknowns in the decision to keep or trade.

Give us a call if you have any questions.

Fuel Injection Keeps Getting Better for Charleston Motorists

Charleston residents know that engines burn fuel to operate. Fuel is pumped from your fuel tank to your engine where it is squirted—or injected—into your engine's cylinders. This is the function of the fuel injectors.

There are two ways to inject fuel into an engine. Fuel needs air to burn, so in the first method, fuel is injected into a port and allowed to mix with air—and before it is drawn into the cylinders. In the second method, fuel is injected directly into the cylinders and mixes with air after it enters the engine.

Direct injection engines burn fuel more efficiently than conventional engines. Some models can deliver the power of a V8 with the economy of a V6.

For example, in one family of engines, the conventional version (a V6) delivers about 250 horsepower. The direct injection version delivers over 300 horsepower and gets about the same . The turbocharged version delivers 350 horsepower.

Why the big difference in power? Direct injection systems allow fuel to be squirted into the engine at hundreds of times the pressure of a conventional engine. This atomizes the fuel better (breaks it down into tinier droplets), which means more of it gets burned, which translates to more power for your engine. It also results in cleaner emissions and improved fuel economy.

Fuel injectors are precision instruments. They have to deliver the right amount of fuel at exactly the time the engine needs it. They are also engineered to inject fuel with a specific spray pattern. This spray pattern allows for maximum fuel efficiency and proper atomization.

Direct injection engines require a much higher degree of precision than conventional engines. For this reason, they are equipped with more sophisticated computers.

When fuel injectors get dirty, their precision drops off. The spray pattern won't be precise, and the timing of fuel delivery may be off. This decreases fuel efficiency and fuel economy for Charleston drivers as well as delivering less power to the engine.

Fuel injectors are not cheap to replace. Direct injection fuel injectors are even more expensive. And we're talking a mortgage payment to buy a set of new fuel injectors for a diesel engine.

So keeping your fuel injectors clean is just good auto advice for Charleston residents. The best way to do this is to change your air and fuel filters regularly and practice other habits of good vehicle care and preventive maintenance at Steve & Stacy's Servicenter in Charleston. Cleaning additives in your fuel can also help.

If you do end up with gum or varnish in your fuel system, you'll need a professional fuel system cleaning. This will clean out your whole system, including the injectors. The good news is that with proper maintenance, your fuel injectors will last for a long time.
