A fix for the Shimano Freewheel clunking noises

85-140wt gear oil. I laid the wheel flat, liberally dribbled some on the freewheel and let it seep in. I did this twice and the freewheel is dead silent now. I got the idea from LBS who wanted to use a grease injector made for the old reginas. He indicated that it would slow the wheel down due to the viscosity of the grease. I thought about it and reasoned that gear oil would be heavier than the oil I had previously used which quieted it down but did not eliminate it but lighter than the grease. The gear oil did the trick! The wheel spins on the rack forever and most importantly that annoying clunking noise is gone. It is silent!

Hope this helps...
