I have a murray road bike with I believe a freewheel problem. I was biking uphill at night and all of the sudden tons of terrible noises happen and the back wheel no longer spins. This is the first time I have really taken a bikes rear hub apart so I really don't know what is suppose to be there as I am sure I lost some pieces I couldn't find on the road that dark night. There are links below with pictures to the outside/inside or the freewheel along with the hub. From what I can tell the freewheel looks okay tooth wise but I'm not understanding where the spring mechanism is that is suppose to make the wheel spin with the freewheel. Help and insight would be greatly appreciated on whether I need a new freewheel, freehub, wheel w/ freehub assembly or to take this thing to the junkyard! thanks for all your help before hand!
