How to Determine the Impact of a Scratched Chassis?
2 Answers
When the car's chassis is scratched by an unknown object and it's unclear whether it affects driving safety, it is recommended to take the car to a 4S shop or repair shop for inspection. Below is an introduction to the car chassis: 1. Most repair shops have chassis lifts. After lifting the vehicle, check whether the surface of the chassis is scratched or damaged. 2. If it's just a scratch on the steel plate, simply apply some paint. If the pipes are damaged, a thorough inspection and repair are necessary. 3. When driving on roads with pits, depressions, grooves, or other surfaces that can easily scratch the chassis, slow down and detour. Also, pay attention to curbs and speed bumps on the roadside.
Recently, my car's undercarriage got scraped, and I'm really worried about it. I remember driving on a gravel road that day when I heard a 'screech' sound. After parking, I quickly used a flashlight to check the undercarriage for scratches: if it's just a surface scratch, cleaning it and applying some rust inhibitor will suffice; but if the metal is exposed, especially near the engine or fuel tank, it could easily rust or leak oil. I also drove a short distance to test: any unusual noises when turning? Is the braking smooth? If the car body shakes noticeably, the suspension might be damaged, and it must be sent to a repair shop for inspection immediately. Usually, when driving over bumpy roads, try to go slower to minimize similar damage. Regular undercarriage paint treatment is also necessary; otherwise, rust spreading could shorten the car's lifespan and, in severe cases, affect handling safety. In short, handle minor issues yourself, but leave major problems to the professionals.
