Vibration/Noise when clutch is depressed
 

2013 Scion FR-S
31,000 KM Lots of stop and go city, and highway driving...
Driving style is agressive, but havent done much clutch kicking or hard launching.

I tried searching but couldn't find this exact issue on the forum, but it seems similar to what other people describe as a loose release bearing.

So when i fully depress the clutch pedal in neutral, or in any gear there is a mild vibration and what sounds like a rattle/squeek noise. It sounds like a bearing is loose or worn- but i honestly have no idea.

Has anyone else had this problem? Or know what the problem is? and/or know if it would be covered under warranty?

Thanks in advance guys!

I have the same problem. Need help too!

shouldnt really matter if it's capable to being fixed under warranty where as it "should" be repalced and/or fixed under warranty i would agree with you that there is something wrong if you really are hearing that kind of noise and should take it in to be looked at.

I just got the same exact issue today, but on my aftermarket clutch. Wtf is going on here? Any solutions?

Sounds like a throw out bearing .

Even if it is, what's to prevent it from screwing up again after replacing it?

Post a sound clip of it

A new one would do the trick lol I mean unless you have a upgraded bearing we wont have much of a choice....

That would be preferable. I mean I've got a badass clutch, I hate being subjected to the other weaker parts of the chain. I need to open up my tranny anyway, my shifting has been god awful lately. For some reason it's been acting like the clutch is only getting pressed in 90% of the way, which barely allows for shifting.

Perhaps the clutch cylinder needs to be looked at ? Or the diaphragm of the clutch plate somehow was not aligned correctly?
I'm just giving humble opinion. @Synack

Yep, I agree with Wo6M.

The clutch throw out bearing is the most likely the bad actor.

However, unless it was just a bad bearing, something else (like a bent fork) may have made it go bad.

An "operation" is in order .... :(

The throw out bearing comes into play when you depress the clutch..
Might be worn or damaged if you get constant noise which the clutch depressed.
Some noise is considered normal.. But it should not be loud or excessive...

Time to rip it apart. I wish an aftermarket tranny existed.

Well, I hope you get it fixed up soon.

Back in the day, it wasn't uncommon for a throw out bearing to go bad, especially if the driver rode the clutch or the clutch was badly out of adjustment. Not so much anymore.

Keep us posted on what you find.

I mean I hate to threadjack but I want to list the symptoms here, as I've never had a transmission act like this.

It's normally hard to shift into 1st and reverse. The other gears seem easier to shift into, when the car is in motion.

All of the gears including 1st are easier to shift into when moving, I can just push pressure slowly on the gear until it slides into place. But it's far from smooth. At a dead stop, it's normally damn near impossible to shift into any gear.

Most of the time the clutch will stick going from 3rd into 4th, making 4th grind almost everytime. Yes the clutch gets stuck sometimes, and takes a few seconds to return to fully depressed.

It's much easier to shift at middle range RPM's as opposed to dead stop idle, and high RPM's at or near redline.

Basically the transmission is just acting like the clutch is only getting pressed like 80%, just barely allowing for shifting. Often with the clutch fully pressed down, it will still act like it is partially engaged and the car will move forward.

Now, if this sounds like anything any of you have heard before, please let me know so I can relay the info to the techs.

Sorry OP if this is a threadjack, we just have the same issue going on with the noisy throwout bearing. And your noisy bearing might eventually lead to my current issues.

^......well, I have a simple solution to most all problems ..... and they are usually wrong .....:cry:

(sort of like someone said once ..??)

Maybe if you bleed the clutch system, all will be OK .... ??

Hmmmm I thought about it. I'll see if someone can look at it this Friday, not just someone trying to make money and replace an entire transmission.

May interest you lot in a Toyota tech's observation on the throwout bearing
