So I replaced a rear bushing on Big Red about a year or so ago last summer/autumn. Everything seemed fine after that (turned out to be the tires, not the bushing ;-;. ) but now I've gotten a rattle in the back. Well turns out the previously failing shock finally hit fuck it and had failed completely. But it also seems that the upper bolt holding onto the thing is rattling like made now. I'm also very concerned that the nut on the back of the fork assembly is not actually a bolt. But a welded on threaded bolt that's not supposed to be removed and is welded to the back of the forks. Can anyone confirm this? If it is supposed to be welded can anyone provide suitable threading/size for the nut, and preferably a part number for the bolt as well? Rattle is driving me nuts and so is the shake from the shock.
