Another trick is to cut the bushing, one slice on one side. This allows it to curl a bit and greatly eases pushing it inside the hole you are trying to get it into. Once in you need to push the curled end outwards to fit properly.

Edit: You can also warm it up as suggested and push-in one side enough to allow it slip into the hole. Then use something such as below to push through the middle to fill it out again.

I have a tool that looks like a screw driver except the end has a 90 degree turn and it is pointed. I used this to move the curled end outwards.

Keep us posted,
