What Causes the Abnormal Noise in the FAW Cab?
2 Answers
FAW cab produces a creaking noise, which is caused by issues with the airbag beneath the cab. In such cases, the airbag under the cab should be adjusted. The FAW J6 is a truck model with the engine located beneath the cab, and the truck's cab can also be opened. To enhance comfort, trucks are equipped with airbags under the cab that serve as shock absorbers. More details about the airbag are as follows: 1. The airbag is a rubber product: Rubber products can age and wear out over prolonged use. Therefore, the airbags under the truck cab need to be replaced regularly. Failure to replace them in time can lead to serious malfunctions. 2. Other rubber products: There are many rubber products in vehicles, such as tires, wipers, engine belts, chassis bushings, and sealing strips. All rubber products age over time, so they require regular replacement. Neglecting timely replacement can cause various issues in the vehicle. It is recommended to regularly replace all rubber components during routine vehicle maintenance. Additionally, always opt for genuine parts when purchasing these rubber components.
I've also experienced cabin noises while driving, most commonly from loose interior trim parts. For example, plastic panels on doors or the dashboard may rattle on bumpy roads, likely due to unfastened screws or deteriorated rubber gaskets. Rusty seatbelt buckle mechanisms can also creak, especially noticeable during turns or acceleration. Additionally, an imbalanced air conditioning fan caused by dust buildup produces a humming sound that requires disassembly for cleaning. Personally, I first identify the noise source by listening - like tapping trim panels to locate loose points. For cost-saving solutions, I might tighten screws or apply lubricant myself. However, it's crucial to rule out serious underlying issues, such as vibrations from chassis/suspension problems transmitting to the cabin, which require immediate workshop inspection to prevent part detachment or driving hazards. Generally, these noises stem from daily wear and low-quality materials, so regular cleaning and minor component maintenance can significantly help.
