Are you 100% sure the swing arm is moving George. I have taken mine apart before even though it felt free to move but it wasn't until I actually removed the whole thing that I found it was sticking. If the two o-rings are missing from the pivot pin water gets down there (even when you wask the bike) and it results in the pin rusting plus a bit of aluminium to steel corrosion going on results in the pivot becoming sticky.
Hi Dave, I have both O-rings and I can spin the thing around like those olf football rattles! I've really pulled everything out and cleaned meticulously plus new grease.
