Now we come to the tricky part. You have to take the washer out to get to the rubber bushing.

I did some twisting and turning to get the washer of. I also used the iFixit metal spudger together with a small plier to get it loose.

The washer is bended in the process of taking it out. It is very difficult to get this part out, because it is tightly wrapped around the axel. I flattened by placing it in between two wooden boards together with a hammer

After you have taken the washer off, you can take the rubber off.

Look at the rubber, it consists of two parts, a plastic bushing and a rubber ring. Leave it like this.
