i need to change 3 studs on my G, i went about trying that tonight because it seemed easy. and it was a breeze until, i got to taking off the rotor... i searched the forum and google, pretty much everything tells me to hammer on it, and and to loosen the Ebreak tensioner...(i think thats what it was behind the little rubber plug) but now i have a spring in my rotor assembly and really need to get that rotor off but can not figure out how to, any suggestions?
