It is not a problem if the felt under the car chassis is scratched. Here is an introduction about the car chassis: 1. Introduction: The chassis refers to the combination of the transmission system, running system, steering system, and braking system on a car. 2. Function: It supports and installs the car engine and its various components and assemblies, forming the overall shape of the car, bearing the engine power, and ensuring normal driving. 3. Running system: The function of the leaf spring is to maintain an elastic connection between the frame and the body with the wheels or axle. The function of the shock absorber is to cushion the vibration when the car is subjected to shock. The shock absorber is used in parallel with the leaf spring.
I'm a seasoned repair shop owner. That fabric-like part under the chassis is called the underbody shield, actually made of flexible resin. When it's damaged, the key is to check the location and size. If it's just a small tear on the side, you'll hear a tapping sound from wind leakage at high speeds, and it tends to scoop mud into the engine bay during rain. If the shield under the engine is completely torn, replace it immediately! I had a customer who delayed repairs, and a stone got flung into the pulley system – cost over 8,000 yuan to fix. Always listen for unusual noises from the chassis. If you spot oil stains, lift the car immediately for inspection – universal joints on the driveshaft wear out fast when caked with mud.
My best friend's car had this exact issue last week! We girls know nothing about mechanics, and were terrified when we found the underside fabric torn. Actually that fuzzy fabric layer is sound insulation material - when damaged, you'll notice the engine noise gets louder, especially that annoying droning sound above 60km/h. The worst part is the pest problem - stray cats love crawling through those holes to keep warm in winter. Last time her AC suddenly stank, and the mechanics found three dead rats inside. I suggest temporarily sealing the tear with tape immediately, don't end up like my friend who had to spend 3000 replacing the entire sound insulation set.
Having been into car modifications for over a decade, I've removed no fewer than a hundred sets of underbody protection plates. The OEM felt material does get scratched easily, but don't rush to replace it! For off-road vehicles, I actually recommend switching to aluminum-magnesium alloy plates. Last year on National Highway 318, my car's original plate was shattered by rocks. After upgrading to a 3mm thick metal plate with drainage holes, the ground clearance actually improved. Remember to check three key areas after damage: whether there are scratches on the transmission oil pan, if the steering rack dust cover is cracked, and if the exhaust pipe hangers are deformed. A metal plate can be bought online for just over 300 yuan, much more cost-effective than replacing with OEM parts at a dealership.
