Default Chirping/ringing noise when foot off clutch

I have a 2011 WRX with stage2+ mods and running e85 now. I noticed recently that when my foots off the clutch and if I'm either stopped or rolling slowly in 1st or 2nd I hear a chirping sound (also happens in neutral when stopped). But if I press the clutch in slightly, it goes away. Does anyone have any idea what this could be?

I got the chirp after replacing my clutch. I've read a handful of post that say this is normal. Some say it goes away after awhile, some say it never goes away. I'm living with it for now until I decide to move to a 6mt. When i do I'm getting oem throw out bearing and pilot bearing.

Sounds like the ToB, it's rattling around, then you lightly press on the clutch pedal and make it quiet.
Not a real issue unless it gets a lot worse or you have other clutch related issues develop.
It's sorta like a chirping brake pad, it makes noise when moving, but gets quiet with light brake application.

Is there any way to get in there and tighten it down or something without having to remove the clutch/flywheel?

Not really. You "could" also adjust the rod from the clutch master cylinder to the clutch pedal. Keep in mind it also keeps some pressure on the ToB increasing wear to some extent.

I read in one post abot using a spring to keep tension on the arm thatll reduce the chirping.

Definitely throw-out bearing. You can't really make it better without a whole clutch job right now, but slipping or chattering the clutch too much under power can definitely make it worse.

Something that happened to my first Subaru is that apparently the collar that the throw-out bearing fits into had gotten damaged. So the first clutch job was a timebomb from the day I got it back. The second time the throw-out bearing failed, my mechanic said he bored out the collar and installed an oversized throw-out bearing. That worked awesome.

He likely used a snout repair kit. Basically a tube that fits over the input shaft tube on the trans and a ToB with a larger bore ID so it fits over the tube.
You can likely find it on RockAuto in the manual transmission parts list for various Subaru models.

Same exact thing is happening on my '09 WRX after having a new clutch installed. That noise is driving me crazy!

My car has this rattle since I bought it at 38k miles and its gotten a little worse with time. Now at 65k, good to hear this is fairly common.

DO you know if the installer put a light coat of high temp grease on the tranny snout ? I make a point of doing that, as that's where the TOB slides on.

I also put a small amount in the pilot bearing. Also very small amount on the splines where the clutch rides.

Strange..... I had my clutch done 6k ago and started getting a "chirping" type noise when at idle or driving/foot off clutch. Thought it was a belt tensioner or a pulley noise.

Traced it back to where the clutch fork and the slave cylinder contact.

The Slave piston was rubbing against the fork, I cleaned and re-lubed this contact point and have not heard from it again.

I thought it was my throw out bearing
With your car at idle, look under your tmic and watch the fork move around against the slave cylinder rod.

If there is lube present, it may have dirt or crap in there causing the screeching or rubbing/chirping noise.

Under the tmic there is a boot where the clutch fork is. I had the same issue but it went away when I took that boot off and applied high temp grease with a small paint brush in and around everything I could see.

Be very careful introducing grease into the bell housing. If it gets onto the clutch, you'll be sorry.

The grease used for the TOB on the snout is specifically designed to avoid clutch contamination.

If he did what I do, it's a thin smear of grease on the snout, not a huge glob of grease.
The chances of any of it getting on the clutch is about "0".
"IF" any came off, the pressure plate would toss it to the inside of the bellhousing, not into the clutch.

Like I said. I painted it on with a brush. It's not just squirted in there. No chance of it leaving the clutch fork.

Is this what's chirping for you? If so I have the same issue currently.

Nice!! I never really thought of that? I'm gonna give it a try. The shop that installed it said they would do whatever it takes to fix it, which is great, but if it's something as simple as this... no point in having them pull the transmission all over again.

So I had this same issue I took it to Subaru because I didn't have the time or tools to mess with it. They said it's my TOB as a lot of the others have been saying as well. Luckily it was still under warranty (bought the car used) so I got a pressure plate out of it as well. The noise is still there but much much more quite.

Default Chirping/ringing noise when foot off clutch

Update... I ended up getting this fixed on my car finally. The shop that installed the clutch went back in and replaced the throwout bearing, clutch fork and pivot. We aren't exactly sure which of the three was causing the noise but it's gone now. When the new clutch was put in we didn't change the fork and pivot cause they looked fine. Lesson learned... if you're already pulling the transmission, replace everything so you don't have to do it twice. Luckily I have a good shop and they did for no charge.

Same issue for me. Before replacing the TOB try greasing the contact point or take the slave cylinder off and put the tip of a rubber glove over the protruding tip
