When driving the car to the positioning elevator, the front wheel needs to stop in the center of the turntable for pre-positioning inspection, including tire pressure, suspension and chassis inspection.
then carry out data detection, install sensors on the four wheels, fix the steering wheel and brake pedal, lift the car, set parameter tests, and finally make positioning adjustment. According to the data, make corresponding adjustments to the four-wheel positioning data of each tire according to the degree of deviation. After debugging, check the car on the road.
Precautions for four-wheel alignment
1. When using instruments for four-wheel alignment, please pay attention to confirm whether the positioning instruments in the repair shop are qualified.
2. When carrying out four-wheel alignment maintenance, it is necessary to confirm whether the automobile data used by the maintenance personnel is accurate. The car is updated day by day, and the data is also updated, so it is best to bring the instruction manual when positioning the four wheels, because there are accurate data of the car.
3. After the car is positioned, you need to check the printed data to determine whether the camber angle of the front wheel is within the standard range.
4. The chassis of SUV, pickup truck and minibus is equipped with torsion bar spring. If it is used for a long time, the height of the left and right cars will be inconsistent, so it is necessary to adjust the torsion bar to reach the standard value.
