What Does Wheel Alignment Mean in Car Repair?

Wheel alignment refers to the four-wheel alignment. Four-wheel alignment is based on the parameters of the vehicle's four wheels, adjusting them to ensure good driving performance and a certain level of reliability. Introduction to Front Wheel Alignment: The installation of a car's steering wheels, steering knuckles, and front axle has a specific relative position. This installation with a certain relative position is called steering wheel alignment, also known as front wheel alignment. Front wheel alignment includes four aspects: kingpin inclination, kingpin caster, wheel camber, and toe-in. Introduction to Rear Wheel Alignment: Similarly, the two rear wheels also have a relative installation position with the rear axle, known as rear wheel alignment. Rear wheel alignment includes wheel camber and individual rear wheel toe-in. Together, front wheel alignment and rear wheel alignment are collectively referred to as four-wheel alignment.

Wheel balancing is the process of adjusting the wheel balance to ensure the tire does not become eccentric during rotation. When driving at high speeds, if the steering wheel shakes violently or the car body wobbles, it indicates wheel imbalance. At the repair shop, technicians will remove the tire and place it on a dynamic balancing machine for testing. As the machine rotates, it accurately shows where the wheel is too heavy or too light, and then small lead weights are attached to the lighter side to balance it. This eliminates vibrations, improves driving comfort, and prevents uneven tire wear, extending tire life. If the rim is deformed, it also needs to be straightened. I usually advise car owners not to delay addressing this issue, as it can accelerate suspension system wear and even lead to accident risks, especially on wet and slippery roads during rainy days. It's best to check the wheel balance during regular maintenance or after tire replacement. Spending a little money can bring great peace of mind.

I remember last time when the car hit 80 mph, the steering wheel shook violently. Only after sending it to the repair shop did I learn it was a wheel balancing issue. Wheel balancing means adjusting the weight distribution of the wheels. If the weight is uneven after tire installation, vibrations occur during rotation. The mechanic used a machine to detect the imbalance and then added lead counterweights to the rims, fixing the issue quickly. This process is crucial for daily driving. Neglecting it can affect handling, making the steering wheel unstable and tiring during long drives. In severe cases, tires may wear unevenly, leading to premature failure or increased risk of a blowout. It's advisable for drivers to avoid high speeds if the steering wheel shakes persistently and to seek professional help promptly. This saves money, hassle, and ensures safety.

I'm a new driver, and when I drive fast, the steering wheel shakes violently. My friend said it might be due to uneven wheels and needs wheel balancing. Wheel balancing refers to the process of evenly distributing the weight of the wheels. During maintenance, equipment is used to test the rotational center of gravity of the tires, and then counterweights are attached at the lighter points. This simple treatment eliminates vibrations, making the car drive more smoothly and safely. Regular wheel balancing checks after getting new tires can prevent abnormal wear and extend the tire's lifespan.
