Part of the challenge on cogs 4 and 5 (largest two), they thread off in reverse from the back of the freewheel body, so there is no way to remove them while the freewheel body is still attached to the hub.
Too bad this has been a challenge but they can be real PITA. I had to remove one using the destructive method a week ago.
