Do you want to do dynamic balance and four-wheel alignment?

Let's talk about what is dynamic balance first. As we all know, wheels are composed of tires and hubs. However, due to the existence of the valve and the limitation of mushroom nail and tire repair glue after tire repair, the overall quality of each part of the wheel cannot be exactly the same.

But when we drive, the wheels will run at high speed, so a little mass imbalance will lead to a series of situations and endanger driving safety.

Therefore, in order to avoid this phenomenon or eliminate this phenomenon, it is necessary to make the wheel correct the balance of each edge part by increasing the counterweight under dynamic conditions. This correction process is usually called dynamic balance.

Dynamic balance should be done on professional instruments. After the test, the technician will balance the wheels by adding weight.

When do you need to do dynamic balance?

When you need to do dynamic balancing, you should remember one thing: as long as the tires and rims are removed, you need to do a set of dynamic balancing. In other words, whether it is changing tires, changing wheels or repairing tires, it needs to be done.

After talking about dynamic balance, let's talk about four-wheel alignment.

What is four-wheel alignment?

If the wheels are compared to the feet of a car, then the suspension system is the legs of the car. When all cars leave the factory, the positions and angles of wheels, steering mechanism and front and rear axles are fixed.

However, with the accumulation of mileage and tire wear, these fixed data will change, even a small change will lead to great driving risks.

Therefore, four-wheel alignment is to ensure that the vehicle has good driving performance by adjusting four-wheel parameters.

The specific parameters to be adjusted include toe-in of front wheel, camber of front wheel, caster angle of kingpin and caster angle of kingpin, etc. The rear wheel alignment parameters are similar to those of the front wheel, but most cars are not adjustable.

When do you need to do four-wheel alignment?

In the first case, if you find that your car is turning heavily, shaking, deviating, not straight and not returning to its original position, you must do four-wheel alignment.

In the second case, if you find that your tires have abnormal wear such as eccentric wear, you need to do it.

In the third case, if the vehicle has had a traffic accident and injured the steering system or suspension system, it needs to be done.

However, it does not mean that as long as these situations occur, we will blindly do four-wheel positioning immediately, and abnormal tire pressure will also lead to overweight steering wheel. Serious tread wear can also lead to vehicle deviation, so when considering four-wheel alignment, the exclusion method can be done first.

Moreover, four-wheel alignment does not need to be done regularly like daily maintenance, but depends on the situation.

Dynamic balance is to adjust the wheel balance, and four-wheel positioning is to adjust the suspension parameters.
