Until I opened the manual I was going to say, I have just had to do this on my Enduro, I have the blind puller mentioned above and I ended up cracking the race instead of getting the bearing out, this was cos I thought what was between the bearings was frame material when its actually a washer so I could have let the puller sit deeper into the bearing, I ended up going to the LBS where I got the bike who are a Spesh dealer.
Just loaded up the manual for the Evo though and that axle/spacer thing doesnt look nice! Is it held in place by the bearings which are pressed in from each side?
I would say there is a very active Spesh Evo page over on MTBR, I have just scanned it and cant find an existing post about the bearings, maybe join that and ask your question on their?
