Before I say anything, I want to let you know that I've searched the forums already. I did find a write up on how to get rid of the squeak, but it did not work in my case, so I wanted a final opinion on my issue. The squeak has happened ever since I've owned the car for 16 months, but I was getting annoyed by the noise, so I did what the write up stated.
I unbolted the slave cylinder, took off the rod w/ the boot greased it up and put it back on the first time. It stopped squeaking for maybe ten or so pushes of the clutch. I did this about two times and it didn't work.
The third time I took the rod out and sanded down a couple imperfections that was causing the ball to not be round and smooth. After sanding I used polishing and rubbing compound on the ball to thoroughly clean and smooth it out. I was pretty confident with the newly rounded and smoothed ball pivot, so I greased it up with a nice amount of grease making sure to not be excessive.
After bolting it all up, I press the clutch pedal once, no sound, press it a second time and the normal squeaking sound could be heard.
I saw in the write up that the OP used anti-seize grease for the lube of the ball pivot, so I'm not sue if using STP Hi Temp 500 degree grease would be much different from that.
I understand this could be the throw out bearing, but if it was, then why would the squeak go away for a little when being greased up again?
Thanks in advance, I'm going to go back and have at it again in a few minutes. Also, I'm not sure this is in the right place, but I didn't see an area for "Maintenance".
Edit: I did almost this exact thing from this link, I'm going to grease it up some more and see.
