If you are lazy like me, then you can just remove the plastic cap on the bottom and spray a ton of WD-40 (or the like) in there and the run it through the gears a couple of times. When I got my Wicked Fat recently the bike had been sitting for years and neither side was shifting. Did the above, twice, and its been fine for a year.
What kind of lube did you use after the WD-40 flush?
Cheap, light and strong. Pick two.
