Dynamic 4-wheel alignment is something that every car owner must do. It is mainly related to the driver's safety. The following are several ways to avoid being cheated when doing 4-wheel alignment. I hope it will be helpful to everyone.
① When using a truck detector to perform four-wheel alignment, you must make sure that the repair shop's positioning equipment is up to standard.
② You must make sure that the maintenance personnel have used the correct data for your vehicle.
As cars are upgraded, data is also upgraded, but the update of positioning equipment is usually out of date. Some new cars can only be accurately positioned by selecting some old cars. Bring your car manual when positioning, because there is the accurate data of your car.
③After the car positioning is completed, query the copied data information.
The camber angle of the front tire is within the standard range. It should not be too different, and it should not be too different up and down, because it will cause your car to deviate. In terms of the rear tilt angle, only some very high-end cars have a rear tilt angle of about 8 degrees, because they have excellent power steering systems.
Nowadays, the toe value of the rear tires of high-end cars is adjustable. If the distance index value is too different, your car will deviate.
④ The car is not a standard chassis car, like SUV, pickup truck and small passenger car, they are all equipped with torsion bar springs. If they are driven for a long time, the height of the upper and lower vehicles will be inconsistent. At this time, the torque rod needs to be adjusted to meet the specification.
⑤ Be sure to pay attention not to set the height of the car inconsistent with the original factory specification. If one side is lower, the car will deviate from the direction. If the overall height is too low, the shock absorption effect will be lost. If the height is too high, the car will feel like it is floating. The key is to pay attention not to set the front higher and the back lower.
