Squeaky Clutch

I have a 2007 Jeep Wrangler X that has developed a squeaky clutch in the last two months. I am not having any problems shifting gears, and my clutch feels fine when i depress and release it. The squeaking sounds like it is coming from inside the cabin. I looked underneath the drivers panel and the spring looks like the white grease is drying out or something. I lubricated all of the moving joints and the spring with WD-40 and it quit squeaking for a brief time. The dealership has it right now and is saying I need to have the clutch slave cylinder replaced. Any comments or help with this situation would be appreciated.

I am by no stretch of the imagination a mechanic, but I did just change all of the clutch components on my '97 TJ. So take this for whatever it is worth. First off, I would be really surprised if the slave cylinder on an '07 needs replaced already. Moreover, if that was the problem I would think that you should either have some trouble shifting (i.e. that the pedal might have to travel farther than usual before you could shift) or notice some change in the clutch pedal pressure. If you have an external slave and it needs replaced, you might as well just save the money on labor and do it yourself. The hardest part will be the spring pin that holds the hydraulic line to the cylinder - other than that little thing the rest is a breeze. A new cylinder runs around 70 bucks, so maybe get a quote on what replacing it would cost with labor added in. Anyway, if you are certain that the noise is coming from inside the cab it should not be related to your slave. I am not sure what you mean by "white grease" - if it is what I am thinking it may be then you may have a problem with the master cylinder. More costly part but even easier to change than the slave (at least you can do that standing up). Again, I would be surprised if your master cylinder needs replaced already. Get down to the pedal and push it with your hand and see if you can isolate where the noise is coming from. It may be the pivot point of the pedal itself, it could very well be where the pushrod attaches to the pedal (mine is on there with a cheap-o plastic cage-type clip - not sure about an '07) and I suppose that it is even possible that it is your clutch safety switch. None of those should create any serious mechanical problems - just an irritating noise. Hope this helps a bit at least. Curious to see what you find out.

Just got back from the dealership. I didn't let them change the slave cylinder. I had them grease every moving part on the clutch real good. The mechanic drove it around after he greased it and said the noise stopped. I just drove it back to work and i noticed it still has a slight squeak which im sure will get worse. I also forgot to mention that on my drivers side door I have a water leak that has soaked that side of my jeep more than once. My concerns, which i did express to the dealer today, is that the water traveled down my dash onto the moving parts of the clutch and they are starting to rust. The dealership has tried fixing the leak to no avail. Now that I think it is causing other problems they want to revisit the leak issue again. The leak fixing started while the jeep was still under warranty so now that im at 37500 miles and no longer under warranty I have to get this resolved. They are willing to work with me and keep it all under warranty until this specific situation is resolved. If they would have changed the slave cylinder today and I hadn't mentioned my theory about the leak starting all of this I would have owed them almost $400.

The spring looks like it is lubricated with a white lithium grease or something

$400 to replace the slave? It has got to be an internal slave. In which case, and especially since greasing the clutch pedal has helped a bit, it seems extrememly unlikely that your noise is being generated there. As long as that lithium grease is coming from the spring then you probably have no need to be concerned about the master cylinder. When my throwout bearing went it created problems up the entire clutch line and destroyed the seals in the master cylinder pushing lithium grease out of it onto the pushrod. I would not have thought that they would use that stuff on the spring.

Two things come to mind right now. You could get a hose out this afternoon and spray down the driver's side and then check to see if the leak gets any of your clutch pedal assembly wet or not. I guess that would depend on how bad the leak is and how long it might take the water to travel around. My other thought is that their idea of sufficiently greased and yours might not be the same. I would not be surprised if the tech greased it without disconnecting anything, so he/she might not have gotten grease entirely between the squeaking parts. It may get better as the grease gets worked in there more. Or as you suggest it may just progressively get worse again. You might want to try inspecting that grease job depending on how well you can weasel yourself around to get a look at it all - contortionist skills are a plus. Good thing that you caught the leak while it was still under warranty and it is nice of them to extend the warranty to cover it. Whether or not it is actually related, take advantage of the situation to get them to fix that leak properly now and save yourself headaches later. Best of luck - let us know how it goes from here.

Squeak is back. Its coming from under the boot that covers the rod that goes through the wall to the slave. Clutch still works fine. We had a major rain yesterday and last night. The water leaked on the drivers side again, badly. I have brought it back to the dealership this morning. It will probably be there a few days I'm sure. I will let you know what happens. PS- I tried the weather stripping idea and it did not work.

Mine started about 2 months ago on my 2007. Looks like the clutch is using brake fluid so I toped off the brake fluid and the squeak went away.

Lithium grease stopped it for me for about a year. It's time to re-apply.

Did you have to cut the boot to apply the grease? Mine seems to be inside the sealed boot?

Lubricated all of the moving joints and the spring with WD-40 and it quit squeaking for a brief time.

WD-40 is a short term penetrating oil and a poor lubricant (doesn't last long at all). You'll need a longer lasting grease like what others mentioned above.

WD-40 is great at getting stuff unstuck, but doesn't keep it that way for long.
