What Causes the Humming Sound After the Chassis is Scraped?

[VonArabella]

The vehicle chassis inherently possesses certain impact resistance. If it's only a minor scrape, it typically won't affect the vehicle's performance. However, during high-speed driving, if the chassis scrapes against hard and sharp objects like rocks or sharp tools, it can cause damage such as denting the chassis steel plate, deformation of the suspension structure, or even damage to the steering mechanism, leading to severe consequences. Below are aspects of chassis maintenance: 1. Hazards: Poor chassis maintenance can result in issues like vague steering, oil leaks, and loosening of the overall framework, posing safety risks. 2. Precautions: Maintenance should first focus on checking for rust, as the chassis is directly exposed to rainwater and dust, working in harsh conditions that make it prone to rust. If the chassis is rusted, protective measures such as rustproofing and applying protective paint should be taken.
