Ok so the hub rebuild begins. First task is to take out the drive side cup from both hubs. I've never done this before but did a bit of research and got a bearing extractor that would fit the cup. I used a heat gun to slowly heat up the hub shell and tapped it out from behind. Didn't take a massive amount of effort, just a few solid hits onto something solid and it came out quite cleanly.
I was a bit paranoid that the cups weren't exactly the same, as it seems Campagnolo has a habit of making lots of running changes mid production run creating all sorts of odd incompatibilities that isn't well recorded. Luckily they were exactly the same. Now for the nice clean hubs without cups in them, the insides actually looked quite pristine
Now the job was to press the donor cup into the hub, luckily I had a bearing press which incidentally fit quite well, again I heated up the hub before and it went in with some resistance but quite smoothly
