In cold, when in neutral and the pedal is released, I can hear a whirring/whining sound.

I'm wondering what bearing is this? I'm reading online maybe it's input shaft bearing? Pilot bearing? I'm due for a new clutch soon, is replacing the input shaft bearing difficult?

Any help would be awesome.

Chances are it's the throw-out bearing. When you replace the clutch that can be replaced at the same time.

BTW, why are you due for a new clutch? Is it slipping?

I know I had mostly Toyotas, but I never had to replace a clutch, ever, and I had 2 Toyotas >240,000 miles, and a Honda >220,000. Other cars went well over 100,000 miles on the original clutch.

That because some of us is a little more expert in the art of clutch use...

When I pulled engine from 89 Celica with 355,000....... the clutch disc look like new, flywheel and plate' friction surfaces still look new (original machine marks and all,, no spots or anything).. look like it was taken from box couple week before


I HATE automatic transmissions....

Me too, with a few exceptions. The one in the Accent is OK, but it saps too much of the "power" from the engine, the one in out 1972 Corona was OK, and the one in my Supra is OK...just. Again, saps too much power...

It has been slipping since new and it gets worse and worse. At 70,000 miles, I feel like it will be gone soon. I took it to two different Hyundai dealers and they said it was "normal". I use the clutch nice and smooth and I drive a lot of highway. I know for sure this is an engineering fault.

I got a quote from a mechanic is he wants to charge $600 for clutch change labor. He couldn't find a clutch and told me I have to buy one at the dealer.

I have a bad feeling it'll cost me $900-$1,000 to fix.

Sheesh, I just change my water heater 2 weeks ago and it cost me $1,300. FML

Well, if you're going to do the clutch soon anyway, the tech will be able to tell which bearing is the bad one. Let us know.

Throw out bearing going bad will change sound if you just rest your foot on the clutch. If it is REALLY going south you can sometimes feel a vibration in the pedal that matches the sound you hear.

Anytime I have changed a clutch I always change the TO bearing. Its all labor to get to the clutch, and the bearing is right there.

That little guy should always be replaced with a clutch job. It’s cheap and gets a lot of wear in daily use . Besides , if it goes later you have to pull the
Tranny again and that’s the real cost of the work. Same goes for the pressure plate if it’s got any burn spots in it. Sometimes they get refaced but like most things today it might be better just to replace it if needed or the new clutch may chatter ever after. Any mechanic will know what needs doing.
These things tend to last the life of the car in the last 20 years. Has somebody been riding the clutch,maybe resting their foot on it as a habit? Occasionally though one will just go though like anything else.

Absolutely agree that all 3 parts must be changed but from my experience and the info supplied (without hearing the noise) I can only diagnose the front input bearing as the culprit.
Question? When you drive the car does it make the bearing noise in each gear getting quieter as you move up the gears?

So do i, useless things, just give me 3 pedals.

From what I saw driving around New England for a living, there are a lot of people who have enough trouble with just 2...

Where I live I wouldn't drive anything but an auto. I do love my manual cars but for the daily city traffic auto is the go. Many countries seem to mainly have manual cars but I put that down to 2 things. The cost of repair and the knowledge base to fix them.

Most likely the input shaft bearing as you have worked out. Clutch slip from new normal what a load of crap that is.

Now I'm all messed up. On that website, it says input shaft bearings. I called two transmission specialists and they laughed at me and told me it was definitely the pilot bearing.

Generally speaking, input shaft bearings tend to get noisy in transmissions that are put under very heavy loads like higher capacity trucks. On the other hand, throw-out bearings are not running in an oil bath, are exposed (and designed for) heavy side loads, heat, and the constant change in load from clutch operation. Their failure rate is not necessarily based on time or mileage, but number of operations.

They still shouldn't have laughed. Just saying. :)

Could you please tell me what was your problem diagnosed? I am facing the same issue when clutch is released whining sound start but when apply pressure then sound goes off. Thank you

Let's put it this way:
With pedal depressed, transmission input shaft stops turning, pilot brg & t/o brg turns, no noise.
With pedal out, transmission input shaft turns, pilot brg & t/o brg do not, noise
Transmission side, probably input shaft brg.
