Wolverine broken right analog stick

I'm just asking for help on fixing my wolverine because I dont have the money to replace it; I love the product and would if a had the money. The right analog stick is broken and a small part came off which jingles around inside of the controller which hasn't done much to my knowledge, the real problem just came in today whenever I look around in games the speed accelerates goes up and down and makes it hard to control recoil. Could I take the controller apart? I have several controllers and could interchange parts, any help is appreciated.
