Let's discuss throw out bearing noise...
Only when cold, like backing the car out of the garage, my TO bearing may squeel like a SOB..drive it a through a couple stop signs/light and it may not make another noise all day.
Last owner replace whole assembly couple years ago..certainly not 'worn out'
What actually is the noise? Is it skidding on the pressure plate? The clutch arm? Is it the bearing itself chattering?
Now I ask you this for this reason. My buddy has gone thru 3 TO bearing [LUK] is a 68 Camaro In a week....this time after putting in a new one and it squeeling backing out the garage...he pulled it in and put a different Presure Plate [off the junk pile] and the noise went away.
I don't want to do this job twice [actually not even once]
And suggestions?

I don't know if the helps or not. Two years ago I had the engine and trans out, Replaced the clutch assemble with a Luk unit, but didn't use their bearing. I had a bearing made by GREEN. Do you know anything about the parts that went into your car? How long has this been happening? Other here may have some thoughts.

Check out this thread. I got an american made TO bearig from Jegs, and the noise issue I had is now gone. My noise appeared after only a few hundred miles on brand new install. Evidently there are threads on new bearings that puke out very quickly.

I have never heard of any threads on a TO bearing.
Am I missing something? Dennis

skids, I read the post you mentioned twice. Not to make this a peeing contest, but I did not find a word about "threads on a TO". I'm lost! Dennis

I'm guessing skids means forum threads...not SAE threads..

A throwout bearing won't make noise in reverse backing out of a garage, or going forward, either, unless something is very wrong. Normally, the T/O brg. is not even applying pressure to the pressure plate unless the clutch pedal is pushed in. You should have enough clutch free play so that the bearing isn't running against the pressure plate under load all the time. Normally, a T/O that is bad is noisy when you push the clutch in to change gears. If your car is making noise backing out of the garage, much more likely to be brake noise, etc.

GTO guy, Let me be clear, Noise comes as you push in the clutch to reverse [or go forward] first shot in the morning...maybe the first couple times you stop and go from a stop.
Car does NOT have to be moving in either direction.
two conditions needed...
Car needs to be cold..
Clutch needs to be depressed.
Makes noise 30-40% of the time cold .
1% of the time warm
It IS 100% temperature related. 100% clutch depressed [or riding the clutch as in engaging to make car move] related.
When the car is warm, noise is gone till it is cold again.
It is a squeel not a squeek. It is not coming from the motion of the pedal or linkage.
Noise is in the bell housing.
Looked up the purchase slip this afternoon, From Ecklers, Complete RAM kit, Pilot bearing, release arm spring all replaced at the same time. Less than 5000 miles ago.
Clutch itself works awesome...ceptin' the squeel.

Mine does it also. Hot or cold. If the engine is idling high from the choke, first start up, it does it when I press the clutch peddle. If I hold the peddle down and rev the engine it does it. The worst is when I get the cruise in or car show and shift to reverse it will grind the gears unless I delay the shifting into reverse, in front of everybody. If I'm waiting in line to get to the parking area or sitting at a traffic light it may make a fuss also. Slightly pulsing the clutch peddle usually makes it stop. Actually mine is not so much a squeal but more of a growl similar to a wheel bearing that's been cleaned and is spun with an air nozzle. I've replaced it a couple of times and this is the best so far. I'll change it again one of these days.

karkrafter, that clears things up a whole bunch. I get you now. Sounds like a dry or defective T/O bearing to me.

Mine initially made a squeal when it got warm with the clutch engaged, unless I nudged the pedal up a hair...then it would quit. Also when the clutch was fully depressed it would quit. Ifound that it was a loose Zbar...once I locked the Z-bar into place I did not have any more issues. Of course when I pulled the TO bearing out the lip that rides along the face of the transmission had a bend in it...not sure how that could happen, the clutch fork was attached correctly..... >shrug< New one going in again.
PS the original LUK bearing with plastic housing didn't last 500 miles....

I guess I understand that it IS a bad TO bearing, my question is why does this problem seem so prevalent with reasonably new to bearings?
I don't wait to replace mine and THEN have it squeel an hour,week,month later like so many fellas...there has got to be an answer.
PITA job to do twice, three or more times...

I use a LUK setup from Napa...had to replace the T/O 3 time until i decided on the last time to buy a 'good' steel one...this went on for about a year...i got pretty good at pulling tranny...squeal went away after the 'upgrade...
A little levity on your issue...Cold and Depressed
That's the problem...you need to take "her" out more..
