Since it's all gotta get pressed on it needs all new bits....sorry, it's been a few years (like 8) and I've forgotten what-all there is. Bearing, seal, couple of spacer-looking dudes, abs ring- iirc.
Just make darned sure whoever does it MAKES NOTE OF THE SPACES BETWEEN EVERYTHING BEFORE THEY ARE TAKEN OFF AND MAKES SURE THE NEW STUFF IS PRESSED BACK ON WITH THE SAME SPACING! It matters.
