When the car chassis is scraped, the chassis should be inspected. Here are some introductions about the car chassis: 1. Prevention: When the car is designed, the chassis has a certain impact resistance. The most vulnerable parts of the car chassis are various pipes, such as brake hydraulic pipes and fuel pipes, but these pipes are hidden and protected in the grooves of the chassis steel plate and will not be higher than the horizontal plane of the chassis. 2. Impact with the ground: If the chassis hits protruding stones on the ground, the impact contact surface is point-like, and the protruding stones are likely to touch the pipes in the grooves, causing oil or fluid leakage, which is quite harmful. You can drive the car to a repair shop and have the car lifted for a thorough inspection of the chassis.

Last time I drove over a pothole, the chassis got scraped, which really worried me at the time. I immediately pulled over, turned off the engine, and used my phone's flashlight to check underneath for any fluid leaks. If you see oil leaking or hear any strange noises, don't drive any further—call a tow truck right away. If it's just minor scratches on the surface, I'd still drive to a repair shop and have the mechanic lift the car for a thorough inspection. After all, the chassis houses critical components like the fuel tank and exhaust pipe, so I wouldn’t trust a random roadside stall—I’d rather spend extra to get a full inspection at a 4S shop. Now, I always slow down in advance when approaching rough roads, and I’ve been thinking about installing an underbody guard—it seems like a move.

As a car owner who frequently drives to sites, I've encountered undercarriage scrapes several times. Experience tells me the first thing to do is turn on the hazard lights, slow down, and pull over. Don't rush to restart the engine—first walk around the vehicle to check for oil or coolant leaks on the ground. If there are signs of fluid leakage or exhaust pipe deformation, contact professional roadside assistance immediately. If no obvious issues are found, I'll drive slowly to a repair shop, paying special attention to any warning lights on the dashboard. Mechanics say the oil pan and steering system are the most vulnerable parts of the undercarriage, so applying an extra layer of undercoating every six months provides noticeable protection against rust and impact damage.

Last time I went over a speed bump too fast and heard a loud clunk from the chassis. I didn't pay attention at the time, but the next day I noticed oil dripping in my parking spot. I recommend checking for fluid leaks immediately after any impact, especially for black or green liquids. Even if everything seems fine at the moment, watch out for unusual noises or pulling in the following days. A friend of mine ended up with a damaged transmission costing over 8,000 yuan to repair because he didn't address it promptly. If you're unsure about the extent of the damage, you can take photos of the undercarriage with your for an online technician to make a preliminary assessment. Developing the habit of observing road conditions while driving daily is crucial.

Driving for thirty years, scraping the chassis is quite common. The key is to observe the collision location and intensity: hitting the engine guard plate is usually minor damage, but if it's the fuel tank area, you need to be cautious. I usually test the steering and brakes on a safe stretch of road after a collision to check for any abnormal vibrations. When parking, I place a piece of cardboard under the engine and check for any fluid leaks the next day. If you hear a loud scraping sound from the undercarriage, make sure to check if the exhaust pipe hanger has come loose. Last year, my car's exhaust pipe was damaged because this small part fell off.
