I recently built up a beautiful new touring wheel (36 holes, velocity dyad) around a brand new SRAM i-light generator hub. Biked to school yesterday. The good news is that the generator worked well, noticably charging up my batteries. The bad news is that the hub squeaks loudly once per revolution. I didn't notice this before, but it certainly happens now, even with no load on the bike.

So, I presume I could "service the hub", i.e. open the hub, squirt oil or grease around, and close. Any particular issues I should be aware of with squeaks, or with SRAMs, or with generator hubs?

Thanks,
pete
