If you really have to, just take the back wheel out,and I think the rear shock comes off as well to give you a bit of room,then it's just pull it all out.
No it is not broken but is making some funny noises , and I think or is the ros or the piston bearing that have some kind of lack or worn out, and I am the second owner And I think those parts are the original from factorie, the clutch was change some time befor I purchased it but I am sure the privius owner did not change or boder check out the rod and the piston bearing
