I broke a rear drive side spoke on my mid 90s Bianchi commuter last week. Getting the 6 speed suntour freewheel off was a real pain. I also took the opprotunity to clean/degrease & relube my chain & rear der pulleys (well, just clean/degrease the pulleys as they're plastic).
I rode a nice little 65 mile ride on her Sunday & the drivetrain was squeeking quite badly. I took a look last night & it sure seems like the noise is coming from the rear der area. I dropped some lube into the center of the pulleys, but the squeek is still there.
Also, I noted that while the wheel is spinning without the cranks turning, the sprockets seem to occilate around the freewheel. The freewheel seems to be centered/no occilation, but the sprockets definately wobble as the freewheel spins.
I saw an old thread that suggests this may be normal, but I never noticed it before (of course, I can't say I looked for it). I'm 99% sure I didn't cross thread the cluster when I put it back on the wheel by hand.
Could the squeek & wobble be related? If not, and the wobble is normal, any thoughts on where the squeek might be coming from?
