Car Drift
　　1. Fault Symptoms. Vehicle drift refers to the phenomenon where the vehicle drifts from one side to the other while driving straight with the steering wheel centered. A drifting car is prone to veering off course while moving in a straight line.
　　2. Fault Causes. The steering control valve torsion spring is damaged or too soft, making it difficult to overcome the reverse drive resistance of the steering device, preventing the control valve from returning in time; dirty oil hinders the movement of the valve core and valve sleeve; the valve core of the steering control valve is misaligned from the center position, or although it is in the center position, the gap size on both sides of the valve sleeve groove shoulder is inconsistent; excessive play in the mechanical steering system drive, or loose or excessively worn connecting components; incorrect wheel alignment; incorrect tire pressure or size.
　　3. Fault Diagnosis: When the vehicle drifts, the following methods can be used for diagnosis:
　　(a) Check if the connection points of the mechanical steering system drive components are loose, whether the gaps between components are too large, and whether the drive is loose. Eliminate mechanical steering system faults.
　　(b) Check tire size and adjust tire pressure.
　　(c) Check for dirty fluid. For new or overhauled vehicles, failure to properly follow the oil change regulations during the break-in maintenance often leads to dirty engine oil. Replace dirty oil.
　　(d) Check the steering control valve. Without starting the engine, turn the steering wheel and judge whether the steering control valve is open or moves freely based on the feel. If a problem is found, it should generally be disassembled for inspection.
　　(e) After the above checks, if the vehicle still drifts, check whether the suspension components are damaged, whether the wheel alignment is correct, and whether the wheel rotation is obstructed to determine the fault.
