Do you have a four-wheel alignment? These 7 kinds of four-wheeled positioning can not cure

Do you have a four-wheel alignment? These 7 kinds of four-wheeled positioning can not cure

When driving on a straight road, many owners find that they need to constantly adjust the steering wheel to keep the car straight; if you find out, the car is turning

There is no automatic correction after bending or a large external force is needed to assist the correction; or the steering wheel is shaking, it seems that you need to do four-wheel positioning. But not all the four wheel alignment of the deviation phenomenon can be solved. Do not blindly perform four wheel alignment when encountering the deviation.

What situations need to be done in four rounds?

Four wheel alignment plays an important role in the normal driving of the car. After the car has been running for a period of time, due to various reasons, the tire will be abnormally ground.

Loss, accelerated wear of parts, sinking of the steering wheel, deviation of the vehicle, increase of fuel consumption, etc., and these phenomena are the reasons for the decline in vehicle performance.

In addition to these phenomena, the most effective way to ensure the stability of the vehicle is to do four-wheel positioning, which not only ensures the normal running of the car, but also extends

Long tire life, while saving fuel consumption.

The role of four wheel alignment:

The four-wheel alignment angle is the relative angle between the suspension system and each moving mechanism. Maintaining the correct four wheel alignment angle ensures the straightness of the vehicle.

And maneuverability, improve the steering of the vehicle and ensure the resilience of the steering system, to avoid damage and loss of precision due to improper bearing force. More sure round

The tire is tightly joined to the ground to reduce the tire’s improper wear and wear, ensuring stability during cornering.

Seven situations that cannot be solved by four-wheel alignment:

1, the tire pressure on both sides is not equal

Tire pressures vary and the tires become different in size and will inevitably run off when rolled.

2. Front shock absorber failure

When the front shock absorber of the car loses its effect, it will also cause the car to run off. At this time, the two suspensions of the car will be high and low.

The force is not uniform, so simply doing four-wheel positioning in this case will not be effective. The owner can use a special shock absorber tester to judge before the use of shock absorbers is good or bad.

3. Excessive wear of the chassis components

When the chassis parts of the car are excessively worn, there will be an abnormal gap in the chassis of the car. When the gap is too large, it is easy to run.

Partial phenomenon, so if the owner finds that there is no effect by doing four-wheel positioning, you may wish to find the reason from this aspect.

4. The pattern of the tires on both sides is inconsis

It is best to use the same type of tires for the entire car. At the very least, the two tires of the front and rear axles must be the same, and the depth of the pattern must be the same. another

In addition, the tire must be replaced beyond the wear limit.

5, shock absorber spring

The damper spring deformation is inconsistent on both sides of the deformation, and the damper spring can be judged by comparison after pressing or disassembling.

6, the brake return of a certain wheel is poor

This is equivalent to always applying a partial brake to one side of the wheel, and the vehicle will necessarily run off when driving. When checking, you can feel the temperature of the hub, such as a certain the wheel is much larger than the other wheels, indicating that the brake of the wheel is poorly returned.

7, the overall deformation of the frame

The wheelbase on both sides is too large, beyond the maximum allowable range, and can be measured by a tape measure. If it is out of range, it must be corrected by the calibration table.
