If the vehicle has these situations, do a four-wheel alignment immediately

Mar 11, 2025

In vehicle maintenance and repair, you often hear about the four-wheel alignment. In fact, this project does not need to be done regularly. It only needs to be done when certain faults occur. It does not need to be done when there are no abnormalities. So, In what situations does it need to be done? 

1. The vehicle cannot drive straight

The vehicle cannot drive straight, even if it is driving on a straight road, and needs to constantly correct the direction to drive straight. This is caused by positioning data errors, the angles of the left and right tires are different. Normal tires are facing straight ahead, if they are not facing straight ahead, but facing one side, the vehicle will not be able to drive straight. In this case, four-wheel alignment must be done in time, otherwise it may cause other problems.

2. Steering wheel is not straight

Under normal circumstances, when the vehicle is driving in a straight line, the steering wheel will also be in a horizontal position. If the steering wheel has an angle when the vehicle is driving in a straight line, and it is not exactly in a horizontal position, the steering wheel is not straight.

If there are no other abnormalities, the steering wheel is not straight and will not affect driving, nor will there be any safety hazards. However, many drivers will constantly adjust the direction because the steering wheel is not straight. Therefore, it also needs repair.

The repair method is also to do four-wheel alignment, adjust the length of the steering gear tie rod on the left and right, generally extend one side and shorten the other. Of course, there are a few vehicles whose steering wheels do not have locating pins. In this case, there is no need to do alignment. Just remove the steering wheel, rotate it to the correct angle and then install it.

3. Abnormal tire wear

For example, the inner side of a tire wears faster than the outer side. When this kind of eccentric wear occurs, the life of the tire will be greatly reduced. It used to take 100,000 kilometers to wear the pattern to the limit, but now it only takes 30,000 kilometers to reach the limit on one side. This is because the positioning data of the tire is incorrect.

4. Reduced vehicle driving stability

When driving at high speed or on uneven roads, if the vehicle has obvious bumps, shakes or increased vibrations, this may be due to changes in wheel alignment parameters, resulting in uneven force on the suspension system, which in turn affects the vehicle's driving stability. Another situation is that the steering wheel cannot automatically return to the center. If the steering wheel cannot automatically return to the center, there is a high probability that the positioning data is inaccurate. This will cause some trouble to driving and make the driver more tired.
