F12 A12 front discs or bearing strip

Anybody had the front hubs apart? I've stripped mine by attaching a slide hammer to the wheel studs and with a lot of effort the hub, disc and inner race of the outer bearing detached from the inner race of the inner bearing. These bearings have a collar and shims between them to set load and oil seals either side. Now assembly would be straight forward but there is an oil seal between the outer bearing inner race and hub with a smaller ID than the OD of the bearing. The seal locates in the upright housing and the bearing is very tight on the hub and tricky to get behind with a puller. Theres no way to locate the outer seal when it is sitting between the bearing and hub as the disc and back plate deny access. You could remove the bearing place in the up right followed by the seal and then press the hub/disc into the bearing. The collar, shims and inner bearing could then be refitted but this is a lot of faff to do a disc change or trial set the conical bearings. And getting the whole assembly into the press is cumbersome. There must be an easier way???!!!
