while trying to get my chain tight enough and straight i have noticed that the carrier bearings are shot or close to it, and my parts bike has brand new never ridden on bearings in it. but the sprocket hub is loose on the axle, not sure if the hub is worn or the axle. well got the carrier remved from the good bike and realized i dont have a big enough wrench to get the axle nuts off, and my pipe wrench grew legs and took a stroll into somebody elses toolbox. so what else can i use to remove the axle nuts? anybody?
