I haven't checked this site in a long time, so you may have figured it out by now, but what I got was called a door striker bushing I believe, it was a small tube like your describing and slipped over the striker peg. I think I had to cut the old one off one side, the other side had broken and fell off. They just wear down until the striker for the door doesn't get a good grip on them anymore and lets them rattle.
