Hi guys, I wanted to share my discoveries just incase anyone else was experiencing the same problem. Around 50k miles my R's clutch pedal started squeaking pretty loudly whenever the car got hot - especially after about 30-45 minutes of stop and go traffic, or anytime the weather was above 80 degrees. I took it by the dealer since it seemed like something that would get covered under the powertrain warranty but they weren't able to reproduce it so they did nothing.
Well, I dug in myself and I found out the squeaking was coming from the slave cylinder located just on top of the transmission right next to the downpipe. Here's a video demonstrating how the cylinder operates when you press the clutch.
I peeled back the rubber boot and it seemed like the heat from the exhaust completely burned up the grease. Probably also some dirt and grime got in there over time.
Here's an example of a normal OEM Slave Cylinder that has never been installed. I bought one of these a while back when I was thinking about deleting the delay valve. You guys out there that have done this probably recognize this little guy. An uneducated observation, but it seems like the grease they use here is just normal silicon grease. Not sure how heat resistant that stuff is and how comparable it is to hi-temp grease - I'd be curious to know from anyone that does.
Long story short, I bought some Hi-Temp grease from Autozone, cleaned off the cylinder boot and push rod of the old grease, and re-greased it. Immediately I was able to feel a significant difference in the smoothness of the clutch pedal, and the squeaking seems to be gone!
I'm going to start checking the grease now whenever I change the transmission fluid, since the slave cylinder is literally right next to the transmission fill hole and both jobs require you to take off the airbox.
To do this work, you'll need:
- 5.5mm socket or phillips head screwdriver for the hose clamps on the air box
- 10mm socket
- Some socket extensions
- Needle Nose Pliers (for re-applying the boot)
- Some hi-temp grease
Anyways, I hope this helps some people, especially as we go into the spring and summer months. Good luck and happy modding
