Then carry out data detection, install sensors on four wheels, fix the steering wheel and brake pedal, lift the car, set parameter tests, and finally adjust the positioning. According to the data, adjust the four-wheel alignment data of each tire according to the degree of deviation. After debugging, check the vehicle and road.
Matters needing attention in four-wheel alignment
1, when using instruments for four-wheel positioning, it is necessary to 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, it is necessary to check the printed data to determine whether the camber angle of the front wheel is within the standard range.
4. The chassis of 4.SUV, pickups and minibuses are all equipped with torsion bar springs. If it is used for a long time, the height of the left and right cars will be inconsistent, and the torsion bar needs to be adjusted to reach the standard value.
