How Serious Is It to Scrape the Car's Undercarriage?
2 Answers
If important parts are not scraped, then there is no problem. If important parts are scraped and the damage is severe, it is recommended to take the car to a repair shop and have it lifted with a jack for inspection. For front-engine cars, the more important components are located at the front. There are two placement methods for front engines: one is transverse, and the other is longitudinal. Relevant information about the car's undercarriage is as follows: 1. Introduction: The car's undercarriage consists of four parts: the transmission system, the running system, the steering system, and the braking system. The function of the undercarriage is to support and install the car's engine and its various components and assemblies, forming the overall shape of the car, receiving the engine's power to make the car move, and ensuring normal driving. 2. Maintenance details: In winter, to maintain the undercarriage, thorough cleaning and rust-proof treatment should be carried out. First, the undercarriage must be thoroughly cleaned. If there is excessive mud and dirt on the undercarriage, a degreasing cleaner should be used to wash it once, revealing the undercarriage's original "natural color," so that rust-proof treatment can begin.
Scraping the car's undercarriage is something I think could have significant consequences. Once when I was driving on a rural dirt road, the undercarriage got scraped by a rock, and the sound was terrifying. I immediately stopped to check, lying on the ground with a flashlight to inspect. Fortunately, it was just scratches on the protective plate with no damage to the internal components. The undercarriage houses the fuel tank, brake lines, and wiring harnesses—if the fuel tank gets punctured, there's a risk of fuel leakage and fire. A damaged brake line directly affects braking safety. After that experience, I became extra cautious on uneven roads, especially when driving at night when poor visibility makes it easier to scrape the undercarriage. A mechanic told me that minor scratches can be treated with some rust-proof paint, but for serious damage, it's best to get it checked at a professional shop to avoid potential hazards. The safest approach is to avoid potholes and rough patches while driving.
