Who can rebuild one? I've got one on my Ducati that is about 10yrs old and has lost most (if not all) of it's damping ability, and it leaks a little. The bike has been off the road for a "minor refresh" (which turned into a ground up restoration project) for the last 5 years and this is one of the last things that needs to be fixed.
I *believe* that Lindemann bought up all the Fox service inventory. They'd be my first stop on getting it serviced. 408-371-6151 (unless it's changed since the last time I had to use 'em).
LE can do it and Traxxion should be able to as well. When I had one Thermosman also told me he could do it. When I rebuilt mine a few few years ago you could get parts from Fox. If parts aren't available that may change who can do it.
Carver Performance, a snowmobile place in st. hilaire, MN has indicated they have all the required parts and capability.
never used them but found this site when I had a bike with a fox http://www.daughertymotorsports.com/suspension/foxshock.html
