I know this has been talked about before but i just want to reconfirm before i go and buy parts. Cars got about 40k on it and i've definatly let the clutch fly a few times on the stock axles. And of course now i have the vibration in the floor while accelerating. Will just replacing the axles take care of it or is there some else that should be done? Thanks for the insite.
