I reread the OP where some reservations were expressed about taking the hub apart. Once you do it you will find it's easy. You may find your's has greasy gunk inside it like one of mine did. It was gross. Print out Sheldon Brown's instructions and follow them. The only thing in his instructions I don't care for is the hammer and square punch method of loosening the large right hand ball race that's behind the sprocket. I think the wrench I use is called a "C" spanner. It's circular like a C with a hook on the far open end. I hook that into the notch on the ball race and with a good heave it comes loose. I reinstall it the same way. BTW, not all SA ball races have the small "SA" stamped in one of the notches. I marked the one I have that isn't marked with a center punch so I could reinstall it in the same position it was in. Not sure why that's important but everyone says it is. Of particular importance is only loosening the right bearing cone on the axle one half turn only. Give it a try, you'll sleep better knowing your hub is nice and clean inside.
Edit: I would suggest not taking the pawls on the left end of the assembly out unless you feel a need to they are buggers to get back in place with their little springs.
