1. Look at the steering wheel for jitter

The slight deformation is invisible to the naked eye, and we can't see the same deformation inside the hub. At this time, if you drive your car fast and the steering wheel is shaking, the wheel is likely to be deformed. It is time to do a balancing exercise for safety reasons.

2, the wheel hub

The front edge of the wheel is divided into the inner side and the outer side. The outer side can be seen, but the inner side can't be seen, but you can pay attention to whether the steering wheel is shaking when the speed is high or whether the tire will leak. If one of these two situations occurs again, it means that it is definitely a deformation.

3, the hub cracking

If the wheel is cracked in a large pit, it will definitely be deformed. At this time, when cracking, the deformation must be remembered.

4, tire leaks

If the tire leaks and the tire is not damaged, then the hub is definitely deformed, because the deformation of the hub will result in the tire not being tightly coupled with the tire, resulting in air leakage.

5, tire puncture continues to drive

If the tire puncture continues to drive for a long time, then the wheel hub that caused the puncture will be deformed. It is reasonable to check it out by visual inspection.

Second, how to replace the deformed wheel

1. Our first step is to remove the wheel. This operation seems to be very simple, just loosening the screws on the hub, but the order of removing the screws is exquisite. The hub is a five-screw structure. The diagonal sequence should be used when disassembling, which is equivalent to the step of drawing a five-pointed star. In this way, in theory, the force of each screw will be more uniform, and the deformation of the screw and the mounting hole can be minimized.

2. Take the new wheel hub out of the box and carefully place it on the tire changer to fix it. You can start to put on the tire.

3, "set" This operation seems simple, but when you look at the structure of the tire and touch the material of the tire, you will find that putting the tire on the wheel is a very laborious thing. Looking at the slim body of the maintenance master, we also sweated for him. I saw the maintenance master first brushed the Vaseline on the inner edge of the tire, then placed the tire on the wheel hub, and stepped on the pedal to turn the base. With the fork on the tire changer, slowly put the tire on the wheel and force the tire The edge is pressed into the hub.

4, in the process of the set of tires, the maintenance master said to us while operating: "Banli is useless, the more violent hard sets, the more the tires do not cooperate, must not be anxious." Having said that, do this work Less effort is also no good. Let's take a look at the master. He is already sweating. Although the maintenance master pressed the tire very carefully, the tire was still somewhat "naughty": I thought it was set up for a while, and after turning the base, it suddenly popped up again and could only be pressed again.

5. After putting the tire on the wheel hub, it is necessary to inflate the tire according to the standard air pressure, and check the tightness of the tire and the hub while inflating. As the air pressure rises, the inner edge of the tire is continuously squeezed and gradually conforms to the hub, and the tires occasionally emit a "beep" loud sound of the rubber rebounding hub.
