repacking bearings on SM Pro dirt wheels

I'm attempting to re-grease my wheel bearings on my SM pro dirt wheels. Normally I would pop the spacer seal with a large screw driver. On the SM Pro's the axle sleeve (correct term?) sticks out beyond the spacer. This makes it impossible to get the screw driver in at the right angle. I was able to pop one off but it certainly caused the seal to loose it's shape. Is there a better way to do this with the SM's? Thanks!

"Talon have a press and a shouldered drift so that the alloy spacer do not collapse. If you knock the bearing and spacer out from the disk side, then knock it out the other way. He will almost certainly knacker the spacer so I would suggest he has 1 set of spacer and bearing kits for each hub".

I can see how one removes the bearing from the OEM hub. Use a tool to extract them. With the Talon Hubs there is a tube that the axle runs through. It will not allow you to use the standard tool to remove the bearing.

I can't quite understand what he is suggesting. How do you knock the bearing and spacer out? Won't it just be pressd futher into the hub? Has anyone here delt with Talon Hubs?
