How to adjust the steering wheel bias
Recently, there has been a lot of discussion on the Internet about the deflection of vehicle steering wheels. Many car owners have reported that incorrect steering wheels will affect driving safety. This article will combine hot topics in the past 10 days to provide you with a detailed analysis of the causes and adjustment methods of steering wheel deflection, and provide structured data for reference.
1. Common causes of steering wheel deflection
According to recent car owner feedback and maintenance data, the main reasons for steering wheel deflection are as follows:
| Reason type | Proportion | Typical symptoms |
|---|---|---|
| Uneven tire pressure | 32% | The vehicle is running off track and it is difficult to return the steering wheel to the correct position. |
| Incorrect four wheel alignment | 45% | The steering wheel is incorrect but the vehicle goes straight |
| Suspension system damaged | 15% | Steering wheel shaking and deflection |
| Steering system failure | 8% | There is abnormal noise or jamming when turning |
2. Detailed explanation of steering wheel adjustment method
1.Initial self-test steps
• Check whether the tire pressure is consistent (refer to the value marked on the door frame)
• Observe whether tire wear is even
• Test the steering wheel return strength on a flat road surface
2.Professional adjustment process
| Adjustment items | Operational points | Tools required |
|---|---|---|
| Steering wheel mechanical correction | The airbag needs to be disassembled for angle reset | Torque wrench, special puller |
| Four wheel alignment adjustment | Adjust toe and camber parameters | Positioner, adjustment wrench |
| Steering rod adjustment | Synchronously adjust the length of the left and right tie rods | Open-end wrench, measuring ruler |
3. Comparison of recent popular maintenance solutions
According to the voting data of an automobile forum in the past 7 days (2,341 participants):
| solution | Select scale | average cost | Satisfaction |
|---|---|---|---|
| 4S store professional adjustment | 58% | 200-500 yuan | 92% |
| Chain quick repair shop | 27% | 150-300 yuan | 85% |
| Try to adjust yourself | 15% | 0-100 yuan | 63% |
4. Precautions
1. If the steering wheel is deflected by more than 15 degrees, it is recommended to repair it immediately.
2. If a new car is deflected, it should be dealt with within the warranty period.
3. After adjustment, a road test of at least 10 kilometers is required.
4. Temporary deflection is prone to occur after ice and snow weather
5. Effective tips tested by netizens
• When driving in a straight line on a flat road, observe the steering wheel deflection angle and take photos to record it.
• Use the mobile phone level APP to assist in determining the degree of deflection (within an error of ±2 degrees)
• When adjusting the steering lever, follow the "advance three, retreat one" principle to avoid over-adjustment.
Recent big data shows that complaints about steering wheel problems increase by about 30% in winter, and car owners are advised to check them regularly. If the problem is not resolved after adjustments, it may be necessary to check deeper components such as the steering column or the electronic power-assist system.
