Will scraping the car chassis on a step cause damage?
2 Answers
Whether scraping the car chassis on a step causes damage requires case-by-case analysis. Generally, as long as the chassis guard plate is not damaged or broken, it will not affect the chassis. If the vehicle does not have a chassis guard plate and the chassis is scraped, at best the chassis may corrode and rust, and at worst it may damage structural components of the chassis such as the exhaust, suspension, transmission, and steering systems. The car chassis consists of four parts: the transmission system, running system, steering system, and braking system. Its function is to support and install the car engine and its various component assemblies, form the overall shape of the car, receive the power from the engine, enable the car to move, and ensure normal driving.
Last time I scraped the curb while driving, I got out to check and found several white scratches on the underbody shield. This thing is specifically designed to protect the oil pan, so as long as it's not deformed, there's no need to panic. But don't take it lightly—it's best to get down and check for any fluid leaks, and listen for any metal scraping noises while driving. If you hear a clunking sound from under the front of the car when going over speed bumps, it's likely the exhaust pipe bracket got bent. Last month, my friend kept driving after scraping a step, and the radiator support ended up deforming and puncturing the coolant tank, costing over 2,000 to fix. My advice is to inspect the underbody immediately after a scrape, especially checking the oil pan for any cracks.
