Am I correct? let me know if not. i think change the bearing when clutch is died.

A clutch release bearing takes load on the side when you press the clutch pedal in. The bearing will last a very long time if you don't keep holding the clutch down at the traffic lights, nor rev your engine when you are holding the clutch down.

Sorry to revive an old thread, but I've noticed this same whining clutch engaging noise in my car when taking off in 1st uphill. It's happened 4-5 times in total, but always under the same uphill conditions. Not the greatest thing to notice on the car. :( Especially because she's barely ticked over 41,000km!

I wanted to ask, how exactly does the work out clutch release bearing cause the rumbling noise during gradual, clutch engagement, and why would it be intermittent?

I'm booking the 40,000km service next week - to anyone who's had this problem, have you found a way to reliably replicate it yet?

Edit: The sound is VERY similar to the sound heard in this Youtube video: http://www.youtube.com/watch?v=Ah80_hjjoxI
The only difference is that in my car, it's NOWHERE near as frequent as in his car.

I have the same problem with my 06 euro @ 49,000 km

Feel it's gotta be the thrust bearing making the noise, can't stand it! I also have noticed it gets worse in the cold weather. I will hear the noise about 3-4 times a day.

I have also got the creaking clutch pedal as well. I've read it's the slave cylinder's rubbers, correct me if i'm wrong.

I will be taking her in for a service at honda next week! Should all be covered under warranty

Let me know how you go, as will i. :)

Good luck

I've got the creaking clutch too! I realised it's possible to reproduce the noise when taking off uphill, with load and a bit of clutch slipping. Takes a few tries and will probably wear out the clutch itself, but at least I know I'm not hearing things lol.

It's worse in cold weather for me too - is also getting more frequent. I can't figure out why the thing would have failed after only 41,000km (or 48,000km in your case). My clutch still has quite a bit of life in it. Faulty bearing? Or can this due to bad driving style? I'm pretty careful with the car...

I'm in the same scenario as you, but I'm out of warranty! 2005 model FTL.

The bearing keeps the clutch plate and inputshaft spinning while applying an axial force (along the input shaft) to keep the clutch plate from touching the flywheel. If the bearing is worn, then you get noises due to the unsmooth movement. When taking off, you are having the bearing having that axial load and then gradually applying the spinning motion as the clutch comes into contact with the flywheel. The combination of load and spinning motion causes the noise. One you fully take your foot off the clutch pedal, the bearing is not subjected to the axial force, and the spinning itself doesn't cause the noise.

Do you keep the clutch pedal pressed down at the traffic lights or anytime you are stopped? Do you rev the engine while you hold the clutch pedal down?

Thanks for the info :thumbsup::thumbsup:

Nope - My leg would get too tired! I also knew that it wouldn't be too good for the clutch (probably after reading all your posts on how it's so bad!)

Are there any other possible explanations? I'm guessing previous owner is a possibility, but I doubt that's the cause as he took great care of the car.

my sound sounds like shit.

taking off in first you can hear something grinding

then at 2000 - 2500 theres a rattle coming from the gearbox.

gonna get it checked out this week

i think it is my bearings wearing out.
just did an assignment about gearboxes at uni and what aaronng is saying makes sense to me.

ill probably change the bearing and clutch at the same time.

I know all about the holding the clutch in at the set of lights and also about revving while the clutch is in. How bad that is for the thrust bearing.

The only time i would ever rev with the clutch in is when i rev match or heal/toe on downshift ect.

The SAME problem happend on my 05 accord, never got it fixed and sold it. So never got an outcome from honda on the 05 euro i had.

But, i have heard that honda attempts to blame the driver for the issue. The last thing i want to do is bring it to honda, rip out the clutch and gearbox an they don't fix it under warranty and i have to pay there over inflated prices.

It's really annoying. I'd really like a diagnosis before I decide on a course of action. Does anyone have any idea from the noise in the youtube video I posted? The noise comes on 5 or so seconds in.

If I do need to change the bearing and the clutch assembly needs to be opened up, it makes more sense to do other work to save on labour. I'd like to install a lighter fly (from the JDM type R k20a). However, my OEM clutch has a lot of life left in it, so if possible I'd like to save a bit of money by keeping it in. Is this possible, or does a flywheel and release bearing change have to occur with a clutch change?

The clutch release bearing should give out a screeching sound. Is yours like that vid but higher pitch?

You cannot use a k20a flywheel with the stock clutch and pressure plate because the k20a flywheel is smaller. If you get the k20a flywheel, then change the clutch, pressure plate and release bearing (get a honda OEM one) at the same time.
