Message Hey guys,

I had a quick question.

For reference: I have had the Stage V Southbend SS full face
clutch for about 15K miles now, and has lots of life left on it.

A description of the noise i have: when i put the car in gear to
start moving and I let go of the clutch pedal, there is a short
grinding/rattling noise i can hear, and it goes away when the
clutch in fully engaged. It only happens in lower gears, or
when i am going 20mph and have it in forth gear and hit the
gas.

I recently pulled the tranny out to change out the reverse
sensor switch on the transmission. I also replaced the pilot
bearing while in there (which was a possible suspect for the
noise). I also greased up the clutch fork, input shaft, pilot
bearing and stuff with moly fortified grease (another suspect
since i had used white lithium grease previously).

So now i think i pinpointed the problem:

My question is, When the clutch disc is out, are the springs in
the clutch disc supposed to move at all? I recall one of the
springs could be moved around with my fingers and made a
rattling noise if I shook the disc around. I dont think this is
normal. I dont have a new clutch disc laying around to check
if those springs have any free play.

Thanks for your time!
