What to Do When the Rocker Panel Under the Car Door is Squeezed and Deformed?
3 Answers
The rocker panel of a car is a part that is prone to scratches and damage while driving, especially for models with lower ground clearance, which are more susceptible to squeezing and deformation. The repair methods for a deformed car rocker panel are as follows: 1. Rocker panels made of plastic are relatively easier to repair because plastic products have good shrinkage properties. You can try pouring hot water on the dented area to make it bulge. If the effect is not satisfactory, you can also use some professional pulling tools for the operation. 2. Rocker panels made of metal are usually coated with a layer of particles. Minor dents can be easily pulled out using a pulling tool. If it cannot be pulled out, you will need to go to a 4S shop for cutting, welding new corner materials, and professional repair.
Last time I accidentally scraped the curb while driving, causing a big dent in the lower side skirt of the door. I rushed to the repair shop for inspection, and the mechanic said the deformation wasn't too severe—no need for a full replacement. They could slowly hammer it back into shape using metalworking techniques. First, they gradually pushed out the dented part, then used professional tools to reshape it bit by bit, and finally applied body filler to smooth it out. The entire repair process took three days, and the paint color matching was spot-on, leaving no visible traces. The cost was just over 800 yuan, half the price of replacing it with an original part. Everyone should be extra careful when driving through narrow roads—the side skirts are low and easily overlooked. After the repair, I make sure to pay special attention to this area every time I wash the car, keeping it dry to prevent rust.
Deformation of the lower door sill is actually quite common. I experienced this myself when I reversed into an iron post. The first step is to assess the extent of the damage—minor dents can be temporarily fixed by pouring hot water and gently pushing the dent out. However, my case was more severe, with the metal crumpled. The repair shop technician said this type of deformation could affect the car's structural integrity, making timely repair essential. The repair process requires professional equipment: first removing the door trim panel, then using hydraulic jacks to correct the deformation from the inside, followed by a thorough check of the sealing. After repair, it's advisable to apply underbody armor for added protection. Also, make it a habit to park at least 30 centimeters away from curbs.
