When driving on bumpy roads, the steel plate spring is easily broken. Individual blade breakage generally does not have a significant impact on driving, but if there are many fragments, the steel plate spring cannot withstand the load, the vehicle body tilts severely, and even the wheels may touch the fender bracket or the bottom plate of the trunk, causing inability to drive. If such a malfunction occurs during driving and there are maintenance conditions, the steel plate spring assembly can be removed. The two ends of the broken steel plate can be beveled with a grinding wheel, welded with an electric welding machine, and then ground flat with a grinding wheel. Finally, it can be reassembled for use.

If there are no maintenance conditions, a jack can be used to lift the sunken side beam of the frame, and according to the degree and location of the fracture, a wooden board can be placed between the steel plate spring, frame, and axle, and then tied with iron wire or rope, or fixed with steel plate spring clips. After this emergency response, you can drive slowly in low gear and go to a place with repair conditions for repair.
