Time Out: Suspension Problems in CHERRY HILL

Your vehicle's suspension system has two jobs: to prevent the passengers from getting tossed around inside the vehicle every time it hits a bump in the road and to keep the tires firmly planted on the road around every corner and over every bump.

To see your suspension system, you'll have to look under your vehicle. Anything that connects the wheels to the vehicle's frame is part of the suspension system. They're heavy-duty parts that work hard while you're driving and take a lot of wear and tear. Because of this, you should have your technician at Joe D'Auria's Auto look at them once a year as part of your preventive maintenance routine. A good time for it is every time you get your alignment checked.

If your suspension is in trouble, you often feel it in how your vehicle drives. You should get a check of your suspension system: if the vehicle pulls to one side or wanders, if the steering is erratic, if your ride isn't as smooth as it should be, or if your vehicle handles poorly. Uneven tire wear can also indicate worn parts in your suspension system. If your shocks are leaking oil then they definitely need to be replaced. All in all, if you don't feel in control when you're driving, go get your suspension inspected.

Shocks and struts wear out. Wheel bearings may need to be repacked every few years. Some parts of your suspension may need to be lubricated whenever you change your oil. Preventive maintenance is the key to keeping your vehicle under control. Good care can prevent accidents for CHERRY HILL drivers.

If you are in an accident, even a minor one, it can damage your suspension system or knock your wheels out of alignment. Even hitting a curb, pothole or large rock can damage your suspension. A wheel balancing or alignment won't correct a suspension problem, and after any suspension work, you may need to get an alignment.

At Joe D'Auria's Auto, we advise CHERRY HILL drivers never to procrastinate on getting their suspension system repaired. A damaged suspension system can lead to loss of control of a vehicle in an emergency situation and serious accidents.

Potholes are unsightly nuisances around CHERRY HILL, but they're also a major cause of suspension damage for CHERRY HILL vehicles. To avoid this, CHERRY HILL drivers should always keep their tires properly inflated. This gives the tires maximum resiliency. When you're driving around the CHERRY HILL area, avoid potholes if possible. If you can't avoid one, then slow down before driving over it. Slower speeds limit pothole damage. But if you're a little late detecting a pothole, don't brake on top of it. This will throw the vehicle's weight forward and increase the damage.

The suspension system may not be pretty to look at, but it provides you with a safe, comfortable ride — as long as you maintain it properly. You don't have to show it off, but you should be proud of it.

Timing Belt

Ever heard the sad tale of a staggeringly steep repair bill from a broken timing belt? Bad news. Let's take a lesson from their woes and remember to think about our timing belt.

First, let's review what a timing belt does. The top part of the engine over the cylinders is called the cylinder head. The head contains the valves. There's at least one valve that lets the fresh air into the cylinder. This air, mixed with fuel, burns to create power. Then another valve or two will open to allow the exhaust out of the engine. Each cylinder has 2 to 4 valves - that's 12 to 24 valves for a V-6, up to 32 values on a V-8. The opening and closing of the valves is done by a camshaft. The timing belt uses the rotation of the engine to drive the camshaft which opens and close the valves. It's called a timing belt because it has to be adjusted to rotate the camshaft to keep proper time with the engine so that everything's in sync.

The timing belt is a toothed rubber belt. But some vehicles use a timing chain or timing gears instead of a belt. Timing chains and gears are much more durable, but vehicle manufactures are using belts more because they are quieter - and cheaper. If you have a small or mid-sized passenger car, crossover or mini-van, chances are you have a timing belt.

Unfortunately, timing belts fail without any warning. That shuts your engine down right away. Your pros at Joe D'Auria's Auto can inspect your timing belt and look for cracks and looseness. But getting to the belt to take a look can be almost as much work as changing it on some vehicles. That's why manufacturers recommend replacing the belt from time to time. For most vehicles it's from 60,000 to 90,000 miles or 95,000 to 145,000 kilometers. If your owner's manual doesn't specify an interval, ask your service advisor at Joe D'Auria's Auto.

Someone we know, who shall remain anonymous, has had two timing belts fail. The first was while he was waiting at a stop light - that repair cost several thousand dollars. The second was while driving on the highway - that one cost more than twice as much. Both had the cars out in the shop for three weeks. His cars had what we call "interference engines," meaning that the valves and pistons are very close to each other. If the timing belt slips even one notch, the pistons will slam into the open valves. That's why our friend's highway failure was so much more - his engine was traveling so fast that the valves were smashed and they chewed up the cylinder head.

A non-interference engine will just shut down if the timing belt breaks. You're stranded, but the engine doesn't suffer permanent damage. In both cases, our hapless friend was just a couple oil changes past the recommended interval for changing the timing belt. This is one of those things that CHERRY HILL drivers just cannot put off. Now replacing a timing belt is not cheap - but repairs for a broken belt can be far more expensive.

The team at Joe D'Auria's Auto recommends CHERRY HILL drivers check their owners' manual ASAP - especially if you have more than a 60,000 miles or 95,000 kilometers. You may need to get that belt replaced right away. And on many cars, the timing belt drives the water pump. So, it may be a good idea to replace the water pump while you're at it because 90% of the work required for the new pump is already done with the belt change. Doing both at the same time saves you a lot of money because as they say, "timing's everything."

Stop It! You Need Good Brakes

Good brakes are obviously very important. If you've ever had your brakes go out while you're driving around the CHERRY HILL area, you'll know how terrifying it can be. Today we'll focus on how to tell when you have a brake problem and how to make good repair choices.

Often, the first indication that something's wrong with the brakes is an unusual sound. It could be a squeal, chatter or grinding sound.

Some brake pads have a little piece of metal embedded in them that will make a squeal or chirping sound when the brake pads have been worn down to the point that they need to be replaced. It's an early warning indicator.

When you hear that sound, schedule an appointment at Joe D'Auria's Auto soon.

Now a chattering sound is more urgent. That usually indicates that something is loose. It could be a brake pad or even the brake calipers. If one of those parts falls off, you could have some serious trouble stopping the vehicle. It would be a good idea to park it until you can get into the shop.

A grinding noise usually means that the brake pad is completely worn away and the metal parts of the brake are rubbing directly on the metal brake rotor. That means the rotor is being damaged and will need some work. More on that later.

Another warning sign is that your brake pedal may feel soft and spongy – or it may even feel very hard to push in. Both could mean trouble. And of course, you may get a dashboard brake warning light.

Now when it comes time to replace your brake pads, you have a choice to make. You can get the same pads that came standard on your vehicle. You can expect the same performance and durability as with the pads that came on the car from the factory.

Now you can also get a budget brake pad. Sometimes CHERRY HILL drivers insist on lower cost pads. That's OK if the budget demands it, but you need to be aware of the tradeoffs. Lower grade pads are usually noisier, so you'll have to live with more noise when you apply the brakes. They also tend to generate a lot more brake dust, you know, that black dust that accumulates on your wheels. And they probably won't last as long either. In our opinion, that's a lot of compromise for just a few dollars in savings.

You can also choose to buy premium brakes pads at Joe D'Auria's Auto. These perform at higher specifications than the factory pads. You can expect quieter operation, less brake dust and better stopping power.

Now, getting back to the rotors. The rotors are the discs that the brake pads clamp down on to stop the vehicle. If you've been driving with completely worn brake pads, you've scratched grooves into the rotors. If the grooves aren't too deep, the rotor can be resurfaced. A thin layer of metal is cut off the surface of the rotor to make it smooth again.

Now, if the grooves are too deep or if the rotor has already be resurfaced before, there may not be enough material to resurface and still have a rotor that's thick enough to safely stop the vehicle. In that case, the rotor will have to be replaced.

Something that's often overlooked is the brake fluid. Your manufacturer has a recommended schedule for evacuating the old brake fluid, cleaning the system and refilling it with fresh brake fluid. This is really important to brake performance.

So here's the bottom line: if you suspect, inspect. If you notice any of these warning signs, have your brakes inspected at Joe D'Auria's Auto in CHERRY HILL. Your service advisor can help you make the repair decision that's right for you.

How Your Check Engine Light Works

Have you ever had an experience like this in CHERRY HILL, NJ? You drive through the one of those automatic car washes. When you get to the end, where the dryer is blowing, your Check Engine light starts flashing!

You fear the worst, but within a block or two, the light stops flashing, but stays on. By the next day, the light is off.

You wonder; "What was going on?" Well, it's actually a good lesson in how the Check Engine light works.

Your air intake system has a sensor that measures how much air is coming through it. When you went under the high-speed dryer, all that air was blasting past the sensor. Your engine computer was saying, there shouldn't be that much air when the engine is just idling. Something's wrong. Whatever's wrong could cause some serious engine damage.

Warning, warning! It flashes the Check Engine light to alert you to take immediate action.

It stopped flashing because once you were out from under the dryer, the airflow returned to normal. Now the engine control computer says the danger is past, but I'm still concerned, I'll keep this light on for now.

Then the Check Engine light goes off in a day or two.

The condition never did recur, so the computer says whatever it was, it's gone now. The danger is past, I'll turn that light off.

Now a flashing Check Engine light is serious. You need to get it into Joe D'Auria's Auto as soon as possible. But if it stops flashing you can wait a few days, so you have time to see if the problem will clear itself or if you need to get it checked. How does the computer know when to clear itself?

Think of it this way. The engine control computer is the brain that can make adjustments to manage the engine. Things like alter the air-to- fuel mix, spark advance and so on. The computer relies on a series of sensors to get the information it needs to make decisions on what to do.

The computer knows what readings are in a normal range for various conditions. Get out of range, and it logs a trouble code and lights up the Check Engine warning.

The computer will then try to make adjustments if it can. If the computer can't compensate for the problem, the Check Engine light stays on.

The computer logs a trouble code. Some people think the code will tell the technician exactly what's wrong.

Actually, the code will tell the technician what sensor reading is out of parameters. It can't really tell him why, because there could be any number of causes.

Let's say you're feeling hot. You get your heat sensor out – a thermometer – put it under our tongue and in a minute or two you learn that you have a fever of 104 degrees F (40 degrees C).

You know your symptom – a fever – but you don't know what's causing it. Is it the flu, a sinus infection or appendicitis?

You need more information than just that one sensor reading. But it does give you a place to start and narrows down the possible problems.

There are reports on the internet telling you that you can just go down to an auto parts store and get them to read your trouble code or buy a cheap scan tool to do it yourself.

There are two problems with that. First, the computer stores some trouble codes in short term memory and some in permanent memory. Each manufacturer's computer stores generic trouble codes, but they also store codes that are specific to their brand.

A cheap, generic scan tool, like you can buy online or that the auto parts store uses, doesn't have the ability to retrieve long-term storage or manufacturer specific codes. Your CHERRY HILL, NJ, service center has spent a lot of money on high-end scan tools and software to do a deep retrieval of information from your engine control computer.

The second problem is that once you've got the information, do you know what to do with it? For example, a very common trouble code comes up when the reading on the oxygen sensor is out of whack.

So the common solution is for the auto parts store to sell you a new oxygen sensor — which is not cheap — and send you off on your way. Now your oxygen sensor may indeed have been bad and needed replacing. But the error code could have come from any of a dozen of other problems.

How do you know the right solution? Back to the fever analogy, do you need surgery or an aspirin? Leave it to the pros at Joe D'Auria's Auto. Give us a call and let us help you resolve your check engine light issue.

CHERRY HILL Air Conditioning Service

Working up a sweat is a great thing to do in a gym around CHERRY HILL, but not in your vehicle. When CHERRY HILL residents' vehicle AC Systems have a problem, they'll often feel it right away. The question is, how long do you put up with it? You know, the old comfort versus cost dilemma. But a more comfortable drive around NJ has a lot of benefits, and keeping the AC System well maintained can help prevent repairs.

A common cause of AC failure is water and air in the system. The system does not work as well with air in it. And water can cause rust that leads to damage of the A/C components. Also refrigerant, the stuff that makes the air cold, can leak out, reducing the efficiency of the system and making it work harder to try to cool the air. That is why periodically evacuating the air conditioning system and recharging it keeps the proper amount of clean refrigerant in the system for CHERRY HILL residents, so it cools better and lasts longer.

CHERRY HILL drivers should also run the air conditioner regularly, even in the winter, so that it lubricates itself and keeps the seals from drying out. The seals can crack and that leads to leaks. Your vehicle's owner's manual will have recommendations for how often to service your air conditioner. Some service centers also have this information as part of their computer databases. Your friendly and knowledgeable Joe D'Auria's Auto service advisor can give you more information.
