Grinding noise from clutch
When car is cold and I depress or hold the clutch between 3" to fully against the carpet while putting int ogrear i hear this horrible SCREEEEECH!!!!! noise. If I slam the clutch pedal to the floor it goes away. It only occurs when engine is cold. At 4-5" to bottom of pedal travel the cluch is completely disengaged so I do not know why the hell this is happening.

Re: Grinding noise from clutch (rollavette71)
Yup thats what is sounds like.
Might as well replace the clutch when you do this as you have probably damaged the pressure plate.
Gotta love a $20 dollar part that causes a couple hundred in damagewhenit goes bad.
Buy a high quality throwout beaaring. I bought the centerforce once when I orginally put in My centerforce clutch it cost extra but it was still working on its second clutch when the engine went bad.

You don't really need to change anything but the bearing if you don't have the cash. If you do it yourself all it will cost is the cost of the bearing and an afternoon. And alot of swearing.

Re: Grinding noise from clutch (Cali,68,L-79)
1. Drop Tranny
2. Pull flywheel - have resurfaced - approx. $50
3. Replace disc, pressure plate, throw-out bearing, pilot bearing/bushing
Cost depends on vendor - maybe $200-$300?
4. Put it all back together. Be sure to use the alignent tool when bolting up the disc and pressure plate. And use good fasteners on the flywheel and pressure plate. Chase all threads before torquing up.
Good luck!

Here's something that MIGHT work, depending on your car.
#1Remove driveshaft.
#2Support trans on a floor jack with good wheels on it.
#3 Unbolt trans and slide it back and down far enough to get the input shaft out of the throwout bearing and the trans out of your way.
#4 Reach inside the hole where the trans is and feel around for the throwout bearing. It will be attached to the clutch fork with two cheesey clips.
#5 Slip the throwout bearing OFF the clutch fork and pull it out the hole where the trans goes.
#6 Take the new throwout bearing (I think they cost around $20) and clip it on the clutch fork.
#7 Slide the trans back in making sure the input shaft goes THROUGH the throwout bearing. (That's the trickiest part).
#8 Bolt up the trans and driveshaft and away you go.
If you have trouble getting the trans back in just twist the input shaft a little so the gear teeth line up.
Most GM stick shifts have an inspection plate on the bellhousing. That may help you with lining the input shaft of the trans with the throwout bearing. But it's not really difficult to find the hole. I could make a nasty remark about how to make the hole easier to find, but I better not ;)

:iagree:
Dep left out step 1.5 : Support back of engine with piece of wood or cutoff broomstick before removing trans to prevent contact of distributer with firewall or fan with shroud.

Re: Grinding noise from clutch (FeedVaal)
If budget does not allow a new clutch you can get by with only replacing the throwout bearing.... but its while-you-are-at-it-itus. Its easier to replace the clutch now while it is out.
Do not drive it until it is fixed, as you are damaging the pressure plate everytime it grinds.
I payed $450CA for a centerforceII so if you want to get by with a clutch replacement, just get a budget replacement unit from your local autoparts store should only run $200 or so including cleaning of the flywheel.

Re: Grinding noise from clutch (Cali,68,L-79)
SCREEEEECH!!!!! noise
I agree replace bearing, cheap even a $35, no other parts to buy only labor.
If it goes bad again, maybe it will be at a better financial time.
Good luck.

Re: Grinding noise from clutch (trw)
TRW, Where did I say the screech noise wrecked the pressure plate?
IF you Throwout bearing is shot... it probably means the bearing is seizing to some extent( I get that from the screech noise, as a loose bearing does not go screech). That seize will damage the fingers of the pressure plate. I have experienced this first hand. The bearing will take the brunt og the damage but the fingers will incurr damage also.

Re: Grinding noise from clutch (MikeC)
Okay okay...let's not get all snippy with each other. We agree the bearing needs to be replaced soonish. Doesn't matter if it's a screech or whine or hiss...it's noise that SHOULDN'T be happening. And yes...I forgot to mention supporting the engine. Now if everyone is done splitting hairs and whining, let's let David get his car fixed :)

Crust must be very thin...like Holy Communion.
Sausage and maybe pepperoni. Even though I was born and raised in the Chicago area, I never got into that thick "Chicago style" pizza.
