The Straight and Narrow: Power Steering Service at TJ's Auto Center Inc.

Service to a vehicle's power steering system is part of preventive maintenance for  Rockford auto owners. This system provides power to the steering wheel so you can turn it with ease. Without power steering, all of the power to turn your vehicle's wheels would have to come from you.

The central element of most power steering systems is a pump. The pump pressurizes the power steering fluid, and it is this pressure that provides auxiliary steering power. A belt connected to the engine usually powers the pump, although some systems use an electric pump. Some newer vehicles have an electric motor that directly provides the power steering boost.

Pressurized fluid moves from the pump to the steering gear through a high-pressure hose. A low-pressure hose returns fluid to the pump. Power steering fluid cleans, cools and lubricates the system.

Rockford drivers should remember that fluid levels in the power steering system should be checked at every oil change. Low fluid levels can damage the pump, which can be expensive to repair. Low fluid levels may also indicate a leaky hose in the power steering system, so it is a good idea to inspect the hoses, especially if your fluid levels are low.

Power steering fluid breaks down over time, losing its effectiveness. It also gradually collects moisture, which can lead to corrosion in the steering system. So the fluid needs to be replaced occasionally. You should check with your owner's manual or ask your service advisor at TJ's Auto Center Inc. to learn how often this fluid should be replaced.

When your fluid is replaced, your technicians at TJ's Auto Center Inc. will remove the old fluid and replace it with new. Power steering fluids are not all created equal; the fluid has to be compatible with your hoses and seals. TJ's Auto Center Inc. can ensure that you get the right fluid for your vehicle, or you can consult your owner's manual.

Signs that your power steering system is in trouble can include the following: a steering wheel that is hard to turn, auxiliary steering power that cuts in and out, or a whining sound coming from the pump. Also, drivers in Rockford who are not topping off the power steering fluid on schedule may hear squealing coming from the engine belts.

To protect your steering system you should never hold the steering wheel in the far right or far left position for more than a few seconds at a time. This can wear out your pump in a hurry.

Preventive maintenance for your steering system primarily involves the power steering components, but your steering system has other parts that can wear out or be damaged by rough Illinois driving conditions. Such parts include the ball-joint, idler arm, steering gear, steering-knuckle and tie rod. Signs that they are in need of attention include play in the steering wheel, a vehicle that wanders, uneven tire wear and a steering wheel that is off-center. Rockford drivers should have their alignment checked annually. This check-up can reveal bent or damaged steering components.

Problems with Suspension Solved at TJ's Auto Center Inc. in Rockford

A vehicle's suspension system is tough. It can last for years and after lots of driving for Rockford drivers. But it can be damaged quickly by hitting a pothole, curb or rock, and it can wear more quickly if you frequently drive off-road or on bumpy roads. A workhorse vehicle — one that hauls heavy loads — is also going to be hard on its suspension system.

Because the useful life of your suspension system contains these elements of unpredictability, it is important for Rockford drivers to have them inspected periodically. Worn, broken and missing parts can be identified during an inspection at TJ's Auto Center Inc. . An ineffective suspension system will decrease the driver's control over a vehicle, so when it is damaged it frequently leads to the worst kind of vehicular damage — dangerous accidents.

The suspension system is composed of springs and shock absorbers (or shocks). Springs suspend the weight of the vehicle above its axles. They allow the vehicle to “bounce” over bumps, which reduces the force of the impact on the vehicle. Shocks reduce the rebound of the “bounce,” smoothing out the ride of the vehicle. They also force the tires to retain constant contact with the road. Shocks are responsible for “handling performance,” or the ease with which the driver controls the vehicle.

The springs in the suspension system are heavy-duty and rarely break or wear out. Shock absorbers are tough, too, but they will wear out.

Your vehicle might be equipped with struts. Struts are a combination spring and shock absorber. Struts, like shocks, have a limited life span.

Inspecting shocks or struts for damage and wear should be part of your preventive maintenance routine. Since a good suspension system is ultimately a safety feature of your vehicle, it's always better to be proactive about its care. In this case, good car care can prevent accidents.

There are some signs that will warn you that your suspension system may be in need of attention. One of the signs might be a cupped wear pattern on your tires. This is caused by the shocks bouncing unevenly. Other signs of bad shocks manifest themselves in the handling performance of your vehicle. You may notice a drifting sensation when cornering, often referred to as a “floaty” feeling. If the front of your vehicle dips significantly when you brake or if it rocks back and forth after stopping, it's time for new shocks. Your technician at TJ's Auto Center Inc. will check your shocks visually. If they're leaking, they need to be replaced.

Any one of these symptoms warrants an inspection of the suspension system. You should also get your suspension system inspected if you are involved in an accident involving one of your wheels. Rockford drivers should never put off suspension repairs. If you experience suspension system failure, it can cause a serious accident. If one of your shocks needs to be replaced, then replace all four of them. This allows for even handling of the vehicle. Replacing just one of the shocks is rarely good auto advice.

When you replace your shocks or struts, use parts that are equivalent to — or better than — the original shocks on the vehicle. The original equipment was for the weight and expected use of the vehicle, and Rockford drivers should never downgrade.

Upgrading, however, is another matter for Rockford drivers. If your suspension system gets a workout or you just want to improve your vehicle's handling performance, then you should upgrade to a better shock. If you haul heavy loads around Rockford or tow a trailer, then you should definitely be getting heavy-duty shocks.

Servicing High Mileage Vehicles at TJ's Auto Center Inc.

The price of gas and the uncertain economy are both causing Illinois residents to review their finances. More and more Rockford drivers are opting to keep their vehicles longer and put off purchasing a newer car. It is estimated that two-thirds of the vehicles on the roads of North America today have over 75,000 miles/120,000 km on them. And the average age of vehicles is now over eleven years. That translates to some car care issues that many Rockford men and women haven't dealt with in the past.

Older vehicles simply have different maintenance requirements than newer ones. Learning those requirements presents a challenge for people in Rockford because many owner's manuals only publish maintenance schedules up to 60,000 or 90,000 miles (96,000 or 145,000 km). Vehicle owners have to keep good records and be more involved in planning preventive maintenance if they want to keep their vehicles on the road. First of all, any service in your owner's manual that comes with a recommended mileage interval should be continued at that interval.

For example, if it is recommended that you change your oil every 5,000 miles/8,000 km, you should continue to change your oil every 5,000 miles/8,000 km. The owner of an older vehicle has to recognize that his engine is operating under higher stress than a new one. It's just starting to show its age. So many experts suggest that the “severe service schedule” should be followed once a vehicle has racked up some serious road distance. On this schedule, the mileage interval for many services is shortened or should be performed more often. Check with your service advisor at TJ's Auto Center Inc..

Rockford drivers who own older vehicles should also be careful not to neglect or postpone oil changes. A full-service oil change is more critical for an older vehicle than for a new one. Older engines have had a lot of time to build up sludge in their oil compartment, so changing the oil at regular intervals is a must. Skipping an oil change compounds the sludge problem. With a full-service oil change, the vehicle's fluids are also checked and topped off. Your service advisor at TJ's Auto Center Inc. will also let you know if these fluids need to be replaced. Older vehicles have older seals and gaskets, which often develop tiny leaks. Regularly checking fluids will compensate for these leaks and offer a heads-up about any serious ones. So, again, it is important to stay on schedule and not skip or procrastinate a fluid check.

Older seals and gaskets begin to dry out and show their age by becoming brittle. High-mileage formulation oils and fluids can help extend the lives of these gaskets and seals. These products contain additives that recondition seals and gaskets and keep them from leaking. High-mileage formulas cost more than standard products, but in the long run they can pay for themselves by preventing more costly repair bills.

If a vehicle is getting on in years or mileage, its parts are as well. High-mileage car maintenance requires necessary repairs and replacements. Timing belts, radiator hoses, parts of the suspension system, anti-lock brakes, air bags, water pumps, alternators and batteries will not last forever and will wear out in higher-mileage vehicles. They need to be inspected regularly by your friendly and knowledgeable TJ's Auto Center Inc. service advisor and replaced as necessary.

But don't go running for the new car lot just yet. These repairs may sound like a lot, but in total, they're still cheaper for Rockford drivers than new car payments. And if you stay on top of them and budget for them, they aren't as burdensome as it may appear.

If you plan on driving your vehicle into its high-mileage years, there are two relationships you need to develop. The first is with your Rockford service center. TJ's Auto Center Inc. can offer you invaluable auto advice and help you develop a service plan that is right for you and your vehicle. Second, you need to develop a relationship with your vehicle itself. You don't need to name it, but you should become familiar with its noises and idiosyncrasies. Pay attention to changes in its habits such as new or unusual sounds, smells, vibrations, etc. Taking note of such things and sharing them with your service advisor can help stave off a lot of big-ticket repair issues.

As we get older, keeping up with a diet and exercise plan becomes more and more critical to maintaining good health. It's the same with our vehicles. A preventive maintenance plan and smart vehicle care will keep them on the road and keep them safe for a good many years to come.

Bouncy Bouncy ? Are My Shocks Bad?

When Rockford drivers think about preventive maintenance, what usually comes to mind is oil, fluids and brakes. We don't generally think about our shocks or struts, but these auto parts keep our tires on the road.

Rockford drivers don't think about shocks as often as oil changes because shocks and struts last a long time and wear out slowly. They don't need to be checked as often as our brake pads or air filters. By the time your shocks have 50,000 miles (80,000 kilometers) on them, their performance will have noticeable degraded. If you want to restore the handling and ride designed for your vehicle, try replacing your shocks and struts.

Of course, if you drive off-road around Rockford, carry heavy loads, tow a trailer or put in a lot of mileage on poor driving surfaces, your shocks or struts will wear out more quickly. You'll need to replace them more often or upgrade to better shocks.

Your suspension system uses springs and shocks to absorb the “shocks” and vibrations of driving over road surfaces. Springs support the vehicle's weight, suspending it above the axles so the body of the vehicle is protected from most of the bumps on the road. Shocks control the bounciness of the springs by moderating rebound. They also push your tires down onto the road's surface, maximizing traction. Without shocks, your wheels would bounce over bumps and lift against curbs and corners. Shocks are important to the safe handling of your vehicle as well as a comfortable ride. Struts are a combination shock and spring in one unit.

Worn shocks result in lowered vehicle handling performance. If your vehicle “squirms” around corners or gets “floaty” over bumps, then you need to check your shocks. If the rear end of your vehicle squats while accelerating, the front end dips while braking, or one corner sags, you probably need new shocks.

If you're unsure whether you need new shocks, or if you're considering upgrading to a higher quality shock, then consult your friendly and knowledgeable TJ's Auto Center Inc. service advisor. He or she can give you advice on the condition of your shocks and how to match your driving needs to the quality of your shocks.

At TJ's Auto Center Inc. we know good vehicle care is essential to the safety, performance and efficiency of your vehicle. It can improve the comfort of your ride as well.

The TJ's Auto Center 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 Rockford drivers. A lot of us in Rockford 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 TJ's Auto Center Inc. professional. TJ's Auto Center 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 Illinois 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 Rockford, hot or cold Illinois weather conditions and towing.

Off-roading is particularly hard on a vehicle's differential. If you are an off-roader, especially if you cross Illinois 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 Rockford auto repair shops. A smooth ride is the result of proper preparation and smart choices.
