Driving down the road and the clutch pedal goes to the floor in a hurry. Car still drove so I knew it was either the clutch fork or the thow out bearing. Got the transmission out and saw the carnage.

This is NOT a OE TOB. It came off of a rather new Autozone Corvette PP many years ago. Not surprised however it does have a lifetime warranty.

Question. What do you guys reccomend for a good throw out bearing? Are they all the same now days?

my spec 2 did that a couple months ago. i called spec about it and they wer nice enough to send me one off of a spec 3. the spec 3 trowout bearing should fit that clutch if you want to give them a call. the new bearing looks solid as hell

My stock TO bearing did the same exact thing, it bent really bad where the clutch fork was pulling on it. Fortunatley the new one I got was alot thicker so hopefully it will hold up.

If what I have been reading is right, it sounds like the TO is the cause of the infamous T56 marble noise that everyone including myself suffers from. I guess from the bearing having alot of play and movement on the PP portion it causing a rattling noise at idle. Does anyone know of a fix that would solve this.

It looks like there can be an improvement on the c-clip portion that holds the TO on the PP so that it clamps the two together better?

Where did you get this thicker bearing?

I used to have that marble noise on my 94 Z T-56. It only does it with the clutch out of course. It drove me nuts

Got the bad bearing off last night, the square flange did NOT bend or fail. The cylinder where it is bent over the flange, to secure the flange is what failed.

Autozone is going to give me a new (square) bearing. Since its free its going in. If that fails. I dont know???

Update to anyone intersted.
I have welded the top of the square flange to the roll over. This will relieve the stress that caused the old TOB to fail. No doubt this will incresase the strength. The welds will NOT interfere with the fork.

I think I just joined the club with my Mcleod street/strip single disk setup. Only a year old - daily driving no racing.

All we have is the same relabeled chinese junk PP and TO bearings for our cars. I ordered a ACDelco clutch assy and it was made in china. Sent it back, why pay more for the same stuff you can get at the auto parts store.

I have the farking noise as well on both my T/A and my Z28 'vert... Both have McLeod Street Twins with aluminum flywheels, and they both make the rattling "marbles in a can" type of sound with the clutch out and idling...

Now, I bought my Trans-Am brand new, as in ordered it and waited for it, and I cannot ever remember it EVER making any noise like that when it was stock. It was a quiet, smooth, perfect... So, why do ALL the aftermarket clutch setups sound like this?

I wonder if there isn't some sort of change in the throwout bearings from GM stock to what we are running? I do vaugely remembering that the stock throwout bearing having a tear-drop shape to the inner part of the bearing (where the fork rides), thus the bearing would rotate around till the side of the teardrop hit the clutch fork and it stopped rotating. Maybe that is the difference, all of these throwout bearings don't have a detent for them to catch on the fork to keep them from free-spinning.

If that is the case, what a shitty oversight on all the clutch makers parts. Maybe they all got cheap, ie, the stock throwout bearing cost a fortune as it wasn't a generic part, but a app-specific one. If that is the case, then someone has to make a OEM replacement.

Valeo (OEM), AutoZone, SPEC, ZOOM, from what I have seen all have "made in china" TO bearings...

Not aware on any that are not.

Well, I looked it up, I can see why none of the aftermarket stuff uses the ACDelco bearings (part number CT1080), as they are like $200 list, around $150 online...

National makes a OEM replacement that is identical (probably the exact same part) for around the same price ($150)...

All the other "clutch release bearings" are like $20-45 or so... big difference in price...

Hell, I know most of the aftermarket release bearings don't have the big detents, but all we really need is someone to make an aftermarket clutch fork with less space between the prongs so that it "catches" on the inner part to keep the bearing from turning freely...

Hell, if I would have known this I would have just welded material onto the fork prongs myself to achieve the same result. I sure as hell don't want to rip into either of my cars to accomplish it tho...
