Should the Rear Bumper Beam Be Replaced If It's Bent?
2 Answers
Car rear bumper beam should be replaced if it's bent. Here is an introduction to the car bumper beam: 1. Introduction: The bumper beam is a device used to reduce the impact force on the vehicle. Its two ends are connected to low-speed energy absorption boxes with very low yield strength, and then connected to the vehicle's longitudinal beams in the form of bolts. 2. Function: The low-speed energy absorption boxes can effectively absorb collision energy during low-speed collisions, minimizing the damage to the vehicle's longitudinal beams, thereby fulfilling its protective role for the vehicle. 3. Structure: A standard bumper beam structure should ensure that the low-speed energy absorption boxes effectively absorb the energy during low-speed collisions through deformation. The bumper beam is connected to the vehicle body with bolts, making it easy to disassemble and replace.
Last time the rear crash beam of my car got bent in a collision, and I talked to the mechanic who advised replacing it as soon as possible. The crash beam is designed to absorb impact energy, and once bent, it loses its buffering capacity in subsequent collisions, potentially endangering passengers or damaging the car's structural integrity. Concerned about safety, I didn’t hesitate to replace it. Cost-wise, it typically runs a few thousand yuan, depending on the car brand; insurance might cover part of it, but that depends on your accident report. I recommend getting a professional assessment at a specialized shop—they have the tools to measure the extent of the bend. Minor bends can sometimes be straightened, but that’s not a long-term solution. Safety comes first—don’t compromise to save money. Leaving it unreplaced long-term could lead to rust or affect other components, shortening the car’s lifespan.
