What are the effects after repairing a bent car frame?
2 Answers
The effects after repairing a bent car frame are as follows: Reduced rigidity: The frame's rigidity will be worse than before the collision, thus reducing its lifespan. Increased frame fatigue: After repairing a deformed frame, internal stress may still remain, which can easily accelerate frame fatigue, especially in cases of severe deformation. Causing misalignment: If the deformation is severe and the repair is not perfect, it may affect the vehicle's force balance to some extent, potentially leading to misalignment, uneven tire wear, or even tire blowouts. Abnormal noises: There may be occurrences of abnormal noises or resonance. Impact on resale value: If the car is to be sold as a used vehicle, it will definitely affect the resale price.
My previous car had a damaged frame from a collision, and after the repair, it never felt quite right. The steering wheel would occasionally pull to one side, requiring constant adjustments. The most annoying part was the creaking noise from the chassis when going over speed bumps—the mechanic said it was due to the deformed frame causing uneven stress on the suspension. On the highway, the steering wheel would shake violently at speeds above 110 km/h, and four wheel alignments didn’t help. Another major issue was the reduced body rigidity, with noticeably increased body roll during sharp turns. Later, during an inspection, I found out that the wheelbase on both sides differed by 7 mm, causing the tires to wear out much faster. I sincerely advise against aggressive driving in a car with a repaired frame—its safety performance is nowhere near its original factory condition.
