Squeaking Clutch

Hi Everyone Yesterday morning as I was pulling into my office parking I noticed when I depress the clutch there is a squeaking sound kind of like an old door spring that needs lube coming from under the car towards the back. Also it only does it when I drive it for a little bit and it goes away when it cools down. I have been spending all of my office hours since yesterday reading through all the threads here on squeaking clutch and it seems like a common problem but none of the threads gave a direct fix or what actually causes the squeak. I know for sure that its not the pedal helper spring. It is definitely coming from under the car towards the back. p.s. I have don't the clutch and RMS about 3k miles ago. So the clutch is not on its way out either. I'm going to try to get the car on a jack sometime next week but before I start digging in there I wanted some ideas on what to look for.

Mine had the same thing, it was diagnosed to come from the slave cylinder. The mechanic indicated it wasn't an issue, just a squeak. Been squeaking for over two years without an issue

I could not drive a car that squeaks and groans all the time. It would drive me nuts. I would not rest until I had cured the problem even if it meant a new slave cylinder unit. Best to get under there and have someone use the clutch. Scotch the front wheels and use jacks on the rear sides.

Got the same squeak and it is very annoying. Indy could not identify the source during last service but opined it might be the clutch fork?

Add me to the list. The more the merrier I guess :/

I have probably read every thread on this topic and still have not come across and exact cause and fix. As common as it is someone should have found the source and the fix. Everything is a maybe. maybe its the fork maybe its the slave maybe the tranny needs to be dropped maybe the tranny and the engine need to be dropped. maybe non of the above and all we need is some lube (which would be my favorite scenario)

Fixified. Probably what Hurdi meant, but definitely don't slide under the car while it is just up on jacks....

My best guess would be the slave or pilot bearing.

Thanks everyone for your inputs. The squeak has gone away on its own for know but im sure it will come back sooner then later. I just would hate to drop the tranny for a stupid squeak.

Hi, My 996 GT3 is in the shop getting this exact issue addressed. And drum roll... The sound stems from the end of the clutch slave cylinder rod hitting the clutch fork metal on metal. There should be a rubber end piece on the cylinder, but it's not unusual for the piece to tear away. If left uncorrected, the touch point on the fork could eventually wear thin. There will also be metal shavings around your clutch. Is this something that needs your immediate attention? Up to you. For me, much like some others on this board, I can't ignore the sound and addressed it immediately. Repair? The low cost approach would be to replace the clutch slave only. The best approach would be to drop the transmission to inspect inside the bell housing. I'm having a clutch service performed while attending to the parts mentioned earlier. Another source of the sound, although probably less common, is the pressure plate wearing out. I hope that's helpful. -Dan

Thanks Dan My clutch and pressure plate and throw out bearing are less then 3K miles old. But the noise has gone away for now. Soon as it comes back I'll try to get it on jacks and see where its coming from. I hate rattles and squeaks. But I guess its part of the package you get when you have a car stiff as an old bone.

To address the squeak you need to dig deeper into the root cause. While the slave cylinder adds to the noise. The fork assembly tends to be the root of the problem. Porsche updated the hinge and several small parts during the 997 product cycle that addressed the issue. These components are interchangeable and are part of a TSB.
