Hi I have a Trek Fuel 90 from 2001 full suspension bike with a lot of miles on it. Anyhow it has play in the back suspension pivot point that is close to the front sprocket. Just wondering how to remove this and if I need to remove the front sprocket, how to do this? Also need to get a new bushing, will probably have to contact Trek. In addition my back brakes are not working too good. The brake shoes look good but just does not seem to grab the way it used to. I do notice some rim wear from the brakes.
