Unbalanced automobile tires: If the truck does not do dynamic balance after replacing the front wheels, the front wheels will jump and shake when the vehicle is driving at high speed. The solution to this situation is simple, as long as the wheels are dynamically balanced. Front wheel deformation: If the car often walks on potholes, foreign objects inside can easily rub the tire into deformation, resulting in abnormal vibration when the car is driving. If the vehicle shakes due to tire deformation, it is best to replace the tire directly for safety reasons. Damage of front shock absorber: After the front shock absorber fails, the front wheel will naturally be affected when the car is driving normally. In this case, the shock absorber should be inspected and repaired in the repair shop or 4s shop.
You can also observe the gear of the gearbox. If you lose one gear, it should be gone. This should be a problem of gearbox calibration.
