help with shock bearings

[estalero]

I don't know if this is the correct term in English.

Anyway, my left shock bearing is gone. It makes noise while turning wheels for significant amount when maneuvering. And sometimes it will stay in tension and will pull car to one side while driving straight.

Local US car shop told me that it is shock bearing, which I agree, but the quote for parts and repair was very expensive, so I had to put it off for now.

So I would like to ask how to I locate this part and shock rubber cover from parts catalogue like rockauto.com, as I could not find it? Once I locate the parts number then I will search for the parts dealer that would send parts internationally and see if I can get parts cheaper than my local shop.

And is it impossible to replace those myself? I think it is, as I probably need special tools to compress the spring and shock, which I don't have? I’ve never done suspension job myself before.
