The hub is scratched. Is it really reliable to repair the wheel hub?

Always standing by the river, no wet shoes. Even the old drivers miss the sun, rubbing their teeth, knocking on stones, etc. will make our car wheels scratch invisibly. If it is scratched, many car lovers will feel very distressed and even change their wheels. So is it reliable to repair the scratched hub? Do you need to replace it? When is it necessary to replace the wheel hub? Today we will talk about this problem.

Under what circumstances should it be replaced:

If the hub only scratches the surface and the paint falls off, it does not need to be replaced. At the same time, if the scratch area is large, it will not affect the normal use and does not need to be replaced.

In addition, the hub has been worn off, as long as it is not at the extreme edge, don't worry. This situation just needs to be fixed. However, if a piece of the edge is worn off, then the wheel hub should be replaced, because this will affect the air tightness of the tire, and in extreme cases, the tire will burst, posing a safety hazard.

Not to mention the deformation and fracture of the wheel hub, the tire must be replaced, and this situation can not be solved by repair.

In fact, if the wheel hub is not seriously injured, it can be repaired, but taking it to the repair shop for repair is another sum of money. If you want to fix it yourself, keep reading.

We first prepare patching tools, which are available online.

1: clean the hub;

The first step is to clean the hub first, which helps us to check the scratches. If the wheel hub is badly injured, it is too lazy to change it directly. If the hub can still be used, dry it with a towel after cleaning and wait for the next step.

2. Fill the wheel hub scratches;

It is necessary to take out your sandpaper at this time. First use water sandpaper to polish the scratches, and then polish them repeatedly until smooth. Then evenly daub the putty, which can be daubed several times, with an interval of 5- 10 minutes each time, so that the putty can be fully dried.

3: painting and oiling;

The last step is to paint the wheel hub. It is best to cover tires and other eastern areas that do not need painting with paper. When painting, spray a few times more, and spray a little less at a time, so that there will be no painting, and the sprayed paint will be more uniform. After spraying paint and varnish, the car hub will become as bright as new. When painting, then just wait for the hub to dry.

Some people may not pay attention to these repairs, thinking that they will only affect the appearance, but in fact, if the scratches are not repaired, they will rust over time, leading to the oxidation of the hub and ultimately affecting its life, so it is necessary to repair the hub.

In addition, except for aluminum alloy wheels, electroplated and brushed wheels can't be repaired by painting, because the technology and materials are different. These wheels need professional machine tools to repair and need to go to special repair shops for processing.
