Thanks for the replies. I have always run my chain loose. It looks pretty simple. Although it is hard to tell from all of the input what parts I should order. Seal? Bushing? Washer? O-ring? All of the above? I am sure that once I start taking things apart, it will become obvious. I may as well get another new chain and sprockets while I am at it. I hope it is easier than wheel bearings/spacers. Those things have been a real pain to remove on this bike.
Any recommendations on where to get the parts?
