Hello guys me, and a dsm buddie of mine have encoutered a problem on his dsm, He has bough 3 different transmissions because his mechanic told him that the transmission was out, but appearently that wasn't the case! Just today we started up the car(car has all 4 wheels raised) and we put the car in 1st gear..... AS SOON as the clutch starts to grab a little we start to hear a weird LOUD grinding noise from the center of the car(prob X-case??), so we step on the clutch pedal back in. THEN, we put the car in REVERSE and we don't hear any griding noise at all. The grinding usually accurs for some reason when the car is put in gear to move foward. Are these symptoms of a bad x-case? What can I do to make sure its my rear differential or the x-case? ANY help will be greatly appreciated!
