Default The definitive "Stop clutch squeek" thread.

due to popular demand, new pic added!

With all the talk of squeeky clutch pedals on WRX/Sti nowadays, I thought Id post the method I used to completely rid my car of the annoying chirp/squeek emitted from the pedal. Contrary to popular belief, the squeek is NOT from the big resistance spring, and oiling this spring will do absolutely nothing.

To do this you will need:

flashlight
14mm open-ended wrench
silicon grease (preferably gooey kind, not liquid/spray)

The noise originates from 2 plunger-type switches which serve to detect when the pedal is up/down for the starter interlock. These switches are sandwiched unto the clutch pedal lever with two 14mm nuts. The one pictured below is the easier of the two to remove. The second one is a bit higher up and very difficult to see, however the process for removing it is the same.

[IMG][/IMG]

Simply loosen and remove the nut on the side closest to the engine, and unplug the switch from it harness to remove it.make sure to take note of how far the nut was/is threaded onto the switch, so that you know where it should be when you re-install the switch. Then, head to your workbench and take apart the switch by unclipping the clip that holds it together(this is a PITA), you'll see what I mean. you will notice that the switch consists of a shaft which pushes through a pair of metal contacts-when the shaft moves through them quickly, the contacts "snap" together and make the annoying sound you hear when you push your clutch pedal. To silence the switch, take a blob of silicon and cake it over the metal shaft, especially where it meets the springy contacts. This is why you need silicon GREASE as opposed to OIL, as the oil will not provide the "gooeyness" to muffle out the metal-to-metal click.

Re-assemble the switch. You will notice that it still has a slight "click" to it, but once it is back in your car you wont hear it, trust me.

Reinstall the switch by plugging it back in to the harness and then putting on/tightening the nut.

Finally, Double check that the nuts are threaded on far enough onto the threads so that the switch is pressed down when it needs to be(you'll see what I mean, just hit the clutch all the way in with your hand and make sure the switch is pressed down by the end of the clutch travel. If not, simply loosen/tighten as necessary). Keep in mind that if you can take apart and reassemble the switch without the nut moving around too much, you wont need to do this step.

Thats it! repeat the process for both switches and your clutch pedal will be squeek-free!

Yeah, as mentioned the unlubed switched wont hurt anything, it just gets really annoying. And dont worry Chaotic, the only thing I could imagine that would go wrong is that, if the nut that remains on the thread works itself out of position, you would need to tighten it as necessary so that the switch is in the right position. No biggie, would take 5 mins at most.

Hah!
It's almost silly when I get in my car at 6:30AM, dead silence, and I hit hte clutch to start her up. The squeek isn't bad/loud/annoying, but I must admit.......I thought to myself a couple of times already: "What am I driving - a Yugo??"

the clutch squeak on my then-5000 mile my04 was the plunger on the switch at the top of the clutch pedal that gets pushed in when you step on the clutch to start the car. just worked it a little in and out with my finger and the squeak is gone.
jump back, gonna quote myself!

it's so true...

OK, I'm trying to decide if you guys are talking about the same problem I'm having. I have an 05 2.5RS with 26k on the clock. The bottom 2-3 inches of clutch travel creak/sqeak and feel... I dunno... kind of sticky(?)... like there's a lot too much friction. It also feels kind of rough in that same range. The entire rest of the pedal travel is silent and glossy smooth. Does this sound like the problem addresses here?

Ya, that sounds like the problem. I say do the switch repair since its not complicated and you just need greese... If that fails, take it in for warranty service.

Lubing the switch fixed my problem. Of course I did this after I took the spring apart and lubed all the other connections

note: the '03 uses a 14mm wrench.

I'm sure subaru would be glad to take your money, but I think any grease would work. I just used some I had open, which happened to be wheel bearing grease. If you really have no idea, head over to an auto parts store and tell them what you're doing. They can sell you a general purpose grease. Evan WalMart has it. It's really not that critical, you just want something that is viscous enough to stay there (vs. dripping out or evaporating). It's not like a wheel bearing application where you have to worry about grease compatibility.

I have an 04 STI with 27,000 miles. When I push in my clutch it squeeks most of the time and also randomly I can feel some friction/grinding when I push the clutch past 3/4ths the way. Would this problem be fixed by doing this?

If the sound is coming from inside the car, then this is probably it. It's the first thing I'd check.

My squeak turned out to actually be in a different spot entirely... the connecting rod to the clutch cylinder (over to the right past the gas pedal)
