crx with b16 and ys1 w/ lsd. after a hard night of driving my car developed at grind noise, sort of like someone dragging a chain underneath the body of the car. It only happens in gear under load. If I'm moving but in nuetral with the clutch engaged no sound, if I'm in gear but the clutch pushed in, no sound. Doesn't happen in reverse. Doesn't happen when I'm in gear and decelerating, ONLY accelerating. It's loudest in lowergear because they provide the most torque.

For the love of honda, somebody please help me!

 

maybe alternator pulley hitting the frame?
