[Auto Repair Knowledge]Car steering wheel jitter failure and analysis and treatment methods

carsteering wheelJitter is one of the most common vehicle faults in our daily driving process, especially when the vehicle travels between 50,000 kilometers and 70,000 kilometers. This phenomenon is most likely to occur. Steering wheel jitter and body resonance can cause unsafe driving. Bao Chongkai, maintenance technical director of Zhongsheng Toyota, who has been engaged in vehicle maintenance for 17 years and is good at repairing automotive machinery, specially analyzed several common cases that cause steering wheel shaking and provided solutions, hoping to help everyone. Trouble performance: When the car travels at a speed between 80 kilometers and 90 kilometers per hour, the steering wheel will shake, and the vehicle will return to normal when the speed exceeds 90 kilometers per hour. Analysis and processing: This situation is mostly due totireDeformation or vehicleTransmission systemIf it is caused, check whether the positioning angle and toe of the front wheel meet the requirements. If it is inaccurate, adjust it; set upFront bridgeTest the wheel, check the static balance of the wheel andtireWhether the deformation is too large, if it is deformed, replace it. Trouble performance: The vehicle is normal when driving on a flat road, but the steering wheel will shake when it encounters potholes on the road. Analysis and treatment: This is because the tie rod ball end is worn loose or the rubber sleeve at the joint falls off when the car is driving, and the tire becomes irregular due to wear. It should be sent to a professional maintenance point for inspection and replaced damaged parts. Trouble performance: When the vehicle speed is between 30 and 40 kilometers per hour, the body has a sense of shaking, such as the feeling of riding a boat. Analysis and processing: This situation is mostly caused by the tires being deformed due to rubbing, bumping, or being old in daily use, just replace the tires. Trouble performance: suddenly stepped on when driving at high speedbrakeThe steering wheel shakes. Analysis and processing: excessive braking force and frequency may causeBrake disc,Brake padsOverheating, deforming when cold, causing the steering wheel to shake. Generally, the symptoms can be resolved after replacing the brake discs and brake pads. Trouble performance: vehicle body resonance occurs in high-speed driving. Analysis and processing: the common reason is becausetransmission shaftDistortion or cross-connection of the drive shaft is loose, lack of oil and rust. Since the above parts are all under the car body, they are most easily overlooked during maintenance. Therefore, every time you do maintenance, try your best to let the staff put butter on the oilable parts. Related: ·The secrets of saving money for private cars[汽车维修知识]
