Ryan Davey 0 Posted June 29, 2007 My corrado isn't very well, if i dab the excelertor as i'm driving, as the engine eases off there's a knocking sound from under my engine bay (also if i leave it in gear and rock it). Ii'm thinking that it could be the Diff on the way out, can anyone shed any light on this for me is i'm well scared! ie whether i've guessed right, how much it might cost and if i'm going to have a new diff whats the difference in price between the standard one of a limited slip? Thanks for your time.... one VERY worried owner Quote Share this post Link to post Share on other sites
