Wheel alignment is the position of the wheels relative to your car. When properly aligned, the wheels point in the right direction.
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.
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.
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.
You car’s fuel system works with the rest of the engine control system to deliver the best performance with the lowest emissions. Check your car’s fuel system regularly or immediately if you smell gas or suspect a problem.
What does it do? The fuel system transfers fuel from the fuel tank and passes it through a fuel filter for straining before it arrives at the injectors. A pressure regulator controls fuel pressure to ensure good engine performance under a variety of speed and load conditions. Fuel injectors, when activated, spray a metered amount of fuel into the engine. Some vehicles use a return line system to return unused fuel back to the tank.
