1, the automobile steering gear is damaged:
When the steering gear of a car is damaged, there will be some symptoms in the car, such as difficulty in steering or inability to adjust the direction automatically. In this case, it is necessary to readjust the clearance of the steering gear and lubricate it with lubricating oil. If the steering wheel of the car still can't be straightened, go to the repair shop or 4s shop to find a professional to check.
2. The toe-in value is incorrect:
If the car does not do four-wheel alignment after changing the tires, it will lead to the wrong toe value of the car tires, the tires on both sides will not be parallel, and the car will not automatically return to the correct position when turning because of resistance. In this case, the vehicle should be repositioned with four wheels and the toe-in value should be adjusted.
3. Glue damage:
If the rubber pendulum of the car is damaged, it will aggravate the wear on the inner side of the car tire and affect the automatic return function of the steering wheel. In this case, a new rubber pendulum should be replaced.
Precautions for automobile steering gear:
1, turn the steering wheel back when the car stops, otherwise it will cause resistance to the steering gear, and the service life of the steering gear will be affected after a long time.
2. After tire change, do four-wheel alignment in time and check the steering gear.
3. Lubricate the steering gear parts on time.
What happened to the steering wheel?
1. The steering wheel of the vehicle is not straight after a period of use, which is related to tire pressure, tire wear, chassis parts wear and four-wheel alignment. You can measure the tire pressure on both sides first. When the tire pressures on both sides are inconsistent, the vehicle will drive to the side with low air pressure. If the tread wear of the two front tires is inconsistent, it will also lead to vehicle deviation.
2. If there is nothing wrong with the tires, it is recommended to go to the 4S shop to check the use of various parts of the chassis. The change of four-wheel alignment value will also lead to the problem of inaccurate steering wheel after a period of use, or it may be that the tie rod is biased to one side, resulting in inaccurate steering wheel.
The steering wheel of the car needs to be adjusted in time, otherwise the safety hazard is great when driving, and it is very easy to have some bumps.
The difference between steering wheel misalignment and deviation:
Deviation does not necessarily mean that the steering wheel is not straight, nor does it necessarily mean that the steering wheel is not straight. The two can coexist, both of which are deviation and steering wheel deviation. I met someone who said that the steering wheel was not straight, because after he leveled the steering wheel, the car ran to one side, which was considered to be a deviation, but it was actually just the steering wheel.
Therefore, if you want to know whether your car is off course, you should try to find a relatively straight and flat road with few vehicles. It must be a flat road, and there are no potholes, because the wheels will change direction when they run over potholes and bumps, and some roads will have errors in order to drain water.
