Car steering wheel jitter, is one of the most common vehicle faults in our daily driving process, especially the vehicle driving to 50 thousand kilometers to 70 thousand kilometers between the most prone to this phenomenon. Steering wheel shaking, body resonance will lead to unsafe driving. Engaged in vehicle maintenance work for 17 years, good at maintenance of automotive machinery, Zhongsheng Toyota maintenance technical director Bao Chongkai, especially for us to analyze several common cases of steering wheel shaking and provide solutions, hope to be helpful to you.
Fault performance: When the car is running at 80 km/h to 90 km/h, the steering wheel will shake, and when the speed exceeds 90 km/h, it will return to normal.

Analysis and treatment: most of this situation is caused by tire deformation or vehicle transmission system, it is necessary to check the positioning Angle of the front wheel and the front bundle whether meet the requirements, such as misalignment should be adjusted; Set up the front axle to test the wheel, check the static balance of the wheel and whether the tire deformation is too large, such as deformation should be replaced.

Fault performance: The vehicle is normal on the flat road, but when it meets the pothole road surface, the steering wheel will jitter.

Analysis and treatment: this is due to the car in the driving, because of tie rod ball head wear loose or rubber sleeve off at the joint, and tire wear become irregular, should be sent to the professional maintenance point inspection, replace the damaged parts.

Fault performance: When the vehicle is running at 30 to 40 kilometers per hour, the body has a sense of shaking, such as the feeling of a boat.

Analysis and treatment: This situation is mostly due to the tire in daily use due to friction, collision or old and other reasons caused by deformation, replacement of the tire can be.

Fault performance: steering wheel jitter when suddenly stepping on the brake at high speed.

Analysis and treatment: Excessive braking force and frequency may lead to overheating of the brake disc and brake pad, cold deformation and steering wheel shaking. Generally in the replacement of the brake disc, brake pad, symptoms can be solved.

Fault performance: body resonance occurs at high speed.

Analysis and treatment: The common reason is the distortion of the transmission shaft or the loose cross connection of the transmission shaft, lack of oil rust. Because the above parts are under the body, maintenance is the most easy to ignore, therefore, in every time to do maintenance, try to let the staff in the oil can be on the part of the butter.
