The abnormal noise when turning left in the Volkswagen New Santana may be caused by insufficient lubrication of the steering column, resulting in high friction; insufficient power steering fluid; universal joint failure; aging and hardening of the rubber bushings on the chassis suspension stabilizer bar links; or a faulty plane bearing. The exact cause needs to be diagnosed and repaired at a 4S shop. Solutions: When abnormal noise occurs in the vehicle's steering system during use, it is mostly due to the need for lubrication of the steering gear bearings. The owner can remove the shell under the steering wheel, locate the steering gear bearings, and apply an appropriate amount of yellow lubricating grease to complete the lubrication. Modern vehicles are generally equipped with power steering systems, so when the owner notices abnormal noise in the steering system, they should check whether the power steering system is malfunctioning. If the power steering system fails, the owner can opt to replace it. When using the vehicle's steering function, the owner should avoid turning the steering wheel to its extreme limits and refrain from steering while the vehicle is stationary. Correct Steering Wheel Operation Methods: Avoid turning the steering wheel while the vehicle is stationary; try to steer only after the vehicle is in motion. Stationary steering should only be used occasionally in special circumstances, such as when maneuvering out of a parking space. After the vehicle comes to a stop, the steering wheel should be returned to the central position to prevent unnecessary load on the suspension system and tires. When making a U-turn, try to avoid turning the steering wheel to its extreme limits.
