Why does the Besturn B50 make a buzzing sound when turning the steering wheel?
2 Answers
Besturn B50 makes a buzzing sound when turning the steering wheel for the following reasons: Engine abnormal noise: Symptom description: There are many possibilities for abnormal noise in the engine compartment. Most people judge the source of the noise as coming from the engine compartment, usually a sharp metallic sound or a wind-like noise. Solution: Engine abnormal noise indicates that the technical state of a certain mechanism in the engine has changed. It is mainly caused by excessive wear of some parts or improper assembly and adjustment. Some abnormal noises can even predict potential catastrophic damage to the engine. Therefore, when abnormal noise occurs in the engine, it should be repaired in time to prevent the fault from expanding. It should be reminded that if the abnormal noise comes from inside the engine, most car owners cannot solve it by themselves, and it is best to send it to a factory for inspection and repair. Transmission abnormal noise: Symptom description: If there is a "rustling" sound inside the transmission while driving, and the sound disappears when the clutch or accelerator is pressed, and there is a sound similar to whistling when shifting gears. Solution: The transmission has many parts, and the causes of abnormal noise are also relatively complex. When analyzing and judging, pay attention to: whether it is related to a specific speed, such as some planetary gears making noise that is more obvious at around 50Km/h. Whether it is related to certain gears, which is very important for judging transmission faults. If a certain gear makes noise, it must be related to the parts that affect the transmission of that gear; if all gears make noise, it is often a fault of the constant-mesh gear shaft or insufficient transmission oil. Whether it is related to specific actions, such as shifting gears, starting, rapid acceleration, rapid deceleration, turning, etc., are all effective means to judge abnormal noise. Among them, changing speed and direction are particularly important for judging rear axle faults. If the transmission abnormal noise is obvious, it is recommended to send it to a professional repair shop to check the faulty parts and then replace them. Wear abnormal noise: Symptom description: When stepping on the accelerator or brake while driving, there are always some abnormal noises from certain parts of the body. The sound is not loud and does not affect normal driving, but it always makes people worry about where the fault is.
I also experienced a buzzing noise when turning the steering wheel with my Besturn B50, and at that time, the steering felt noticeably heavier. After checking, I found out it was due to a problem with the power steering pump. The power steering pump is responsible for reducing steering effort, and if there's insufficient oil or internal damage, the unstable oil pressure can cause a buzzing sound, as if mechanical parts are rubbing. Loose or worn belts can also produce similar noises since the belt drives the power steering pump, and slipping or vibration occurs when it's loose. If not addressed promptly, the steering system's load will increase, potentially leading to steering wheel stiffness and higher driving risks. It's advisable not to delay—take it to a professional repair shop for diagnosis. Mechanics typically check the fluid, belt tension, and pump condition, and replacing faulty parts usually resolves the issue. Regular driving habits like avoiding frequent full-lock steering can help reduce component wear. In any case, such unusual noises are warning signs, and early intervention ensures peace of mind.
