Ok I feel a little retarded asking this but here it goes. When someone says "you're rear end is shot and needs to be replaced," what is he specifically referring to? Is this the gears or the whole axle or what? I'm trying to find the cheapest way to get this done but need to know what exactly I'm looking for. Again I feel like an idiot asking this but my knowledge is somewhat limited.
Also if anyone has any ideas of where to find what I need I'd appreciate that too.
