Yeah, like toslow said - remove the drive shaft and replace both bearings. That means you usually have to remove the chaincase, too - or at least loosen it up. That means taking the cover off and draining the gear lube, and that means replacing the gear lube and tensioning the chain when you put it back together.
I'm not sure on this sled, but it seems like at least one of the bearings has a locking collar on the inside. Sometimes they're pressed on (usually only one side), There are kits you can buy (such as those offered by All Balls) which include everything you need to replace both bearings. I prefer that, even if the bearings themselves are sourced overseas, because I don't have to worry about buying an o-ring or seal, if one is needed.
If you really want to go the extra mile, the top set of bearings for the jackshaft are also probably due for replacement. Since those require removal of a lot of the same stuff to remove that shaft, you could probably replace those, as well. I remember cutting one bearing off, because it was pressed on and I didn't have a press to get it off. That was a different sled, but be prepared for that. On the other hand, if you remove the jackshaft and the bearing spins fine, you might be okay for now and just put it back together. I've done that, too.
