Has anyone here done this?? have the parts, could use som advice.

Start by getting the tube centre out, I just used a hammer and a suitable sized round bar to drive it out.

The outer steel sealing piece will probably follow the tube centre out on the side it exits, on the side you're hammering just remove it once the tube has passed it.

Outer bearings would come out easy, inner bearing races might be a little harder to get out.
I think I welded something to it and used a slide hammer, can't remember exactly.

What parts have you bought, I guess at least new seals and bearings?

If you look at the other topic in here, "T16user" has loaded some pictures. I've basically got all of what's pictured - except for the bolt and plastic cover / insert.
