Ok some hub surgery. First step was to remove the pitted cup from the drive side and also the donor cup. This wasn't too hard actually, I was a bit worried it might not be so easy. However I used a heat gun to heat up the alloy hub shell and used an expanding collet bearing extractor to get a grip on the cup and tapped it out on the other side with a drift. Took a few decent whacks but came out reasonably quickly on both hubs.
Now pressed the donor cup into the hub, again I preheated the hub to make it a bit easier. Luckily I had a bearing press which more or less fit the cup and it went in quite easily.
Now onto the free hub, the bearings in this were smooth but had a bit of play and were oozing black goo, so had probably ground themselves into oblivion over the years. The first one was easy to pull out as was the spacer, but the next were held in by a circlip without any eyes to use a plier... After trying for 1/2 hour I googled this and a common solution was to drill a tiny 1mm hole in the free hub to push the circle out of the way. Which worked a treat.
Bearings are out, lots of black goo so definitely need to replaced, I noticed the factory ones are SKF which is nice. They are standard bearings, 2x 6801 and 1x 6901
Replaced them with SKF ones as well, apparently there are a lot of counterfeit bearings (yes truly) out there so I bought them from one of the SKF official retailers, not cheap the three bearings were a shade under £50...
Now back to the axle and removing the DS cone, I ordered some alloy/steel tubes off eBay with the correct inside diameter so they could be used to remove and install the cone. Worked like a treat luckily, I was a bit worried for some reason that it might not fit, but the cone fit perfectly
