I have a Doug Nash 4+1 street five speed with a hurst shifter, center force 2 clutch, It was rebuilt just a couple of years ago and know its making a bearing noise, it only makes the noise when the clutch is out and goes away when the clutch is in, the tranny shop said it was internal tranny bearings, but ive been told it could be the throw out bearing in the clutch, my question is has anyone dealt with this transmission and what do you think about my problem? my engine makes about a little over or maybe under 400lbs of torque and about 340 or less horsepower (just a guesss?) a real torquey engine.

classic symtom's for a throughout bearing. they will make noise when not under a load(IE driving down the road) then make noise when you use the clutch(IE at a stop sign).

if it was my car i would get under the car while it was runing in neutral and put a piece of hose on the bell houseing and listen, have a buddy push the clutch peddle a few time's to make sure the noise is in the bell houseing. listen at other part's on the tranny case too to locate the noise.

have the rear end on jack stand's parking break off, so if it slip's in to gear you do not get run over, oh and chock the fron wheel's. be carefull!!!!!

if it is comeing from the bellhouseing area it is most likely the throughout bearing. or maybe the main front in-put shaft bearing(not likely as it would make noise all the time.) good luck hope big gear head post's as he is a pro.

Here is a trick I once used. Adjust the clutch close to the floor. Reach down and pull up on the clutch pedal. If adjusted right this pulls the throw out bearing off the fingers or diaphragm. If the noise stops when you do this it is the throw out bearing.

Make sure you have the proper freeplay on the throwout bearing and that you have a return spring on the throwout fork.
If the throwout bearing contacts the clutch fingers, or diaphragm, it will wear out quickly and make noise.
