Wheel Balance

Wheel Balance

Often confused with wheel alignment, a properly balanced wheel is a beautiful, perfectly tuned wheel-tire combination. This is accomplished by placing measured lead weights on the opposite side of the “heavy spot”—the noticeable tread wear on your unbalanced tire.

How do I know if I need my wheels balanced?

Is your vehicle vibrating at certain speeds, say, between 50 and 70 mph? If so, chances are your wheel is out of balance. One section of your tire is heavier than the other because it’s endured more exposure to the friction and heat of the road. Come in for prompt, professional service—most people are very satisfied with the difference such a simple and inexpensive procedure makes. Look for these signs, and if you find either one, come see us:

• Scalloped, erratic wear pattern on tires.
• Vibration in steering wheel, seat, or floorboard at certain speeds.

Wheel Alignment

Wheel Alignment

Wheel alignment is the position of the wheels relative to your car. When properly aligned, the wheels point in the right direction. Without proper alignment, the wheels resist your steering commands, as well as each other. Alignment also affects gas mileage and tire wear. If your tires are pointed in different directions, they fight against each other and can cause tread wear.

Computerized alignment equipment is used to measure all alignment angles on today’s cars. These include both adjustable and non-adjustable angles. (Non-adjustable angles require repair or replacement of the suspension component.) The most common adjustable angles are:

Toe

This refers to the tilted direction of the wheels toward or away from one another when viewed from the top. Toe is the most critical tire wearing angle. Tires that “toe-in” point toward one another. Tires that “toe-out” point away from each other.

Camber

This refers to the tilt of the wheels toward or away from one another when viewed from the front. Wheels that tilt in toward the vehicle have “negative camber.” Wheels that tilt away from the vehicle have “positive camber.”

Caster

This refers to the angle of the steering axis in relation to an imaginary vertical line through the center of the wheel when viewed from the side. “Positive caster” is the term used when the vertical line is tilted back toward the rear. If it’s tilted forward, we call it “negative caster.” The proper caster angle stabilizes your car for better steering.

Thrust Angle

This refers to the relationship of all four wheels to each other, as well as their relationship to an imaginary center line that runs from bumper to bumper. The term “thrust line” refers to the direction in which the rear wheels are pointed. Thrust angle is correctable on cars with adjustable rear suspensions. If your car has a non-adjustable suspension, thrust angle is compensated for by aligning the front wheels to the rear wheels.

Transmission maintenance

Transmission Maintenance

For those of you who aren’t mechanically-savvy, you probably still understand that transmission problems are among the most expensive repairs required for your vehicle. That’s because your transmission is a complex system of gears that transmit mechanical power to your engine, ultimately determining the rate of speed you travel. Transmissions convert this power from the engine so that it can supply high torque at low speeds, in addition to selecting which gears are appropriate based on the driving conditions. This is especially true with automatic transmissions—by far the most popular transmissions found in the US. Rather than using a clutch to engage the transmission, automatic transmissions use a torque converter (between the engine and transmission) to control the number of gears when driving. Supplying the power to regulate gear action is a demanding task, which is why it’s important for you to contact us, your transmission service specialists. Here are some of the essential maintenance tasks we complete:

• Drain transmission and torque converter
• Refill Automatic Transmission Fluids (ATF) with new fluid

Transmission problems typically arise when regular service is neglected. When fluids aren’t properly changed, heat caused from mileage friction results in rough shifting, accelerated wear, and even complete failure. That’s why it’s essential that you turn to us to make sure that your transmission is lubricated and cooled by the finest quality transmission fluids, installed by our service professionals.

Tire rotation

Tires & Wheels: Tire Rotation

Description: Tire rotation refers to the regular practice of switching the position of each tire on the car.

Purpose: Tire rotation helps to equalize tread wear and is critical to gain the maximum life from your tire investment.

Maintenance Tips/Suggestions: Refer to your owner’s manual for the recommended rotation interval and pattern; generally a rotation interval of 6,000 miles is recommended. The rotation pattern varies with different makes and models, which shows the tire locations during rotation. Some vehicles have different size tires on the front and back or directional tires. This limits the locations that a tire may take on the vehicle. When in doubt, check the owner’s manual or consult a professional technician for guidance. Tire rotation time also offers a good opportunity to have the tires and wheels balanced. It’s another step you can take to maximize your tire investment.

Suspension and Steering Systems

Suspension and Steering Systems

The primary function of your cars suspension and steering systems is to allow the wheels to move independently of the car, while keeping it “suspended” and stable. Any play or uncontrolled motion in these systems results in a deterioration of handling and accelerated tire wear. Vehicle alignment is closely tied to the condition of the suspension and steering systems.

Steering Systems

Worn or loose components affect the ability to control the toe angle, and may result in a loss of directional stability and accelerated tire wear. The main components of a Conventional system are:

• 1. Steering Gear Box
• 2. Center Link
• 3. Pitman Arm
• 4. Idler Arm
• 5. Tie Rods

The main components of a Rack and Pinion steering system are:

• 6. Rack and Pinion Assembly
• 7. Bellows Boots
• 8. Tie Rods

Suspension System

Worn or loose components affect the suspension systems ability to control motion and alignment angles, resulting in a deterioration of vehicle handling and stability, and accelerated tire wear. The main components of the suspension system are:

• 9. Control Arms
• 10. Ball Joints
• 11. Springs (Coil or Leaf)
• 12. Shock Absorbers
• 13. Struts

Oil change

Oil change

Check the owner’s manual to see if your driving habits are considered to be “severe service.” This type of driving requires more frequent oil changes, warns the Car Care Council. Have the oil changed accordingly, usually every 3-5,000 miles. For less wear and tear on the engine, drivers in cold climes (sub-zero driving temperatures) should drop their oil weight from 10-W30 to 5-W30. Your mom and dad would probably suggest simply moving to someplace warmer.

Description: The typical oil filter consists of a high-strength steel housing containing various types of filtering media. An anti-drainback valve prevents oil from running out of the filter when the engine is off. Today’s oil filters have a convenient spin-on design that makes removal and installation easy.

Purpose: The oil filter sifts out contaminants, allowing the oil to flow through the engine unrestricted. Should the oil filter become restricted or clogged with contaminants, they will flow around the filter. This bypassing is a safety mechanism, but you never want to let oil and filter changes go so long that bypassing takes place.

Maintenance Tips/Suggestions: For best results, consult your owner’s manual, but consider that your driving probably constitutes a severe maintenance schedule. Usually, this means oil and filter changes every 3,000 miles or 3 months. If you change the filter yourself, dispose of it properly. Take used filters to a facility that accepts them. Used filters can be crushed, removing the used oil and the steel part of the filter can be recycled. The oil from one used, seemingly innocent filter leaking into a landfill can taint 62,000 gallons of ground water.

Exhaust

Exhaust

Your exhaust system is more than a muffler. It is a series of pipes that run under your car, connected to your muffler and catalytic converter. The main function of your exhaust system is to control noise and to funnel exhaust fumes away from passengers.

In some ways, a car’s exhaust system works like a chimney on your house, directing the byproducts from burning fuel away from the people inside. A car’s exhaust system routes waste gases from the engine to the rear of the car, where they are discharged into the atmosphere. Exhaust gases contain dangerous substances such as carbon monoxide, which can be hazardous if allowed to flow into the passenger housing of the car.

The exhaust system also converts pollutants into less harmful byproducts, reduces the noise of the engine, and directs exhaust gases so they can be used to heat air and fuel before they go into the engine’s cylinders to be burned. Finally, the exhaust system provides just the right amount of backpressure into the engine to improve its fuel-burning efficiency and increase performance. Key components of your exhaust system include:

Exhaust Pipes:

Designed specifically for each car model to properly route exhaust to the back of the car.

Exhaust Manifold:

Acts like a funnel, collecting exhaust gases from all cylinders and releasing it through a single opening. Some engines have two.

Catalytic Converter:

Designed to reduce the amount of harmful emissions products by transforming pollutants into water vapor and less harmful gases.

Muffler:

Metal container with holes, baffles, and chambers that muffles exhaust noise.

Resonator:

Works with the muffler to reduce noise.

Tail Pipe:

Found at the back of the car, the tail pipe is designed to carry exhaust gases away from the vehicle

All components of the exhaust system are connected with a series of clamps, hangers, flanges, and gaskets

Emission Control: Emissions Testing Program

Emission Control: Emissions Testing Program

Description: A program designed to periodically check vehicle emissions to ensure they are within limits. Often referred to as an I/M (Inspection/Maintenance) program, they are used in numerous states and areas as required by the Environmental Protection Agency to improve air quality in those areas. Although the requirement comes from the federal government, states and their associated agencies have some flexibility in the type of test used, vehicle populations to be tested and other program-specific details. Some states run centralized programs that have state-contracted test stations exclusively dedicated to testing. Other states run decentralized programs, where emissions can be tested at local repair facilities. In a few cases, states may run “hybrid” programs using both centralized and decentralized test stations. The latest trend is to incorporate the use of second-generation onboard diagnostics (OBDII) into these programs, in many cases altogether eliminating the need for tailpipe emissions tests.

Purpose: I/M programs evaluate the emissions from vehicles and single out those that are polluting beyond the limits established for certain model years of vehicles. Aside from identifying vehicles with high emissions, such programs advocate proper maintenance to prevent high emissions due to maintenance neglect.

Maintenance Tips/Suggestions: The best way to keep your vehicle environmentally friendly is by performing regularly scheduled maintenance, rather than waiting to correct a problem after your car fails an emissions test. If the SERVICE ENGINE SOON or CHECK ENGINE light appears, have it checked out immediately by a professional technician. Neglecting these warning signs can cause lead to more extensive and expensive repairs.

CV & Drive Axle

CV & Drive Axle

The axle on your vehicle is the structural component that connects two wheels together on opposite sites. It’s a load-bearing assembly that acts like a central shaft, maintaining the position of the wheels relative to each other and to the vehicle body. The construction of your axle is designed according to what your vehicle is built for; trucks and off-road vehicles are equipped with axles that keep the wheel positions steady under heavy stress (ideal for supporting heavy loads), while conventional axles are constructed for the needs of the general consumer. But no matter what you drive, remember that your vehicle’s axle must bear the weight of your vehicle (plus any cargo) and the acceleration forces between you and the ground. So when it comes to axle inspection, we are your source for professional, knowledgeable service—essential for the equipment that carries you and your family to wherever you need to go.

Here is a brief description of the most common axle design:

Drive/CV Axle:

Simply put, a drive axle is one that is driven by the engine. Typically found in modern front wheel drive vehicles, a drive axle is split between two half axles, with differential and universal joints between them. Each half axle is connected to the wheel by a third joint—the constant velocity (CV) joint—that allows the wheels to move freely. This joint allows the shaft to rotate, transmitting power at a constant speed without a significant increase in friction and heat. CV joints are usually dependable, but, as is the case for all of your vehicle’s moving equipment, they do require regular inspection. An easy way for you to tell if you need to see us for axle repair is to go out to a large space (such as a parking lot), and slowly drive in tight circles. If you hear a clicking or cracking noise, you have a worn joint, and it must be repaired immediately.

We will have you back on the road, “click-free” in no time!
