Nevertheless, all I needed to buy were 4 new bearings and 4 seals. The rest of the bits were reusable, including the little shim that fits between the outer bearing and the seal spacer.
I got the outer races out of their housing by MIG welding a bead around the bearing tracks, which then shrunk enough so they tapped out with a long screwdriver onto the weld bead. Total time? Well, the first one took me 4 hours while I figured it all out. The second took just 2. A nice straightforward job!!
Interestingly, XM bearings fit just fine. Here's the GSF invoice showing the part numbers.
