How to solve steering wheel jitter caused by BYD f0 idling?

Vehicle steering wheel jitter is one of the most common vehicle failures in our daily driving process, especially when the vehicle is driving between 50 thousand kilometers and 70 thousand kilometers. Steering wheel jitter and body vibration can lead to unsafe driving. Fault symptoms: When the car is driving at a speed of 80 km/h to 90 km/h, the steering wheel will shake, and when it exceeds 90 km/h, it will return to normal. Analysis and treatment: This situation is mostly caused by tire deformation or vehicle transmission system. Need to check whether the positioning angle and toe-in of the front wheel meet the requirements, and adjust it if it is not aligned; Install the front axle and try to turn the wheels. Check the static balance of the wheel and whether the tire is deformed too much. If deformed, please replace it. Symptoms: The vehicle runs normally on a flat road, but the steering wheel will shake when it encounters a pothole road. Analysis and treatment: This is because the tire becomes irregular due to the wear and tear of the pull rod ball head or the rubber sleeve at the joint when the car is driving. It should be sent to a professional maintenance point for inspection and replacement of damaged parts. Fault manifestations: When the vehicle speed is 30-40km/h, the body feels shaking, such as the feeling of taking a boat. Analysis and treatment: this kind of situation is mostly caused by friction, bump or aging in daily use, so the tire can be replaced. Fault symptoms: high-speed sudden braking causes steering wheel jitter. Analysis and treatment: excessive braking force and frequency may lead to overheating of brake disc and brake pad, deformation in case of cold, and steering wheel jitter. Generally, replacing the brake disc and brake pad can solve the symptoms. Fault symptoms: high-speed vibration of the car body. Analysis and treatment: The common causes are the distortion of the transmission shaft or the looseness and rust of the crosshead of the transmission shaft due to lack of oil. Because the above parts are under the car body, they are most easily overlooked during maintenance. So every time you do maintenance, try to ask the staff to butter the oiled parts.
