Input shaft bearing?

Messages
1,665
I've been reading up and I think I have the signs of an input shaft bearing fault.

Basically I have a rattly type noise (not loud or anything) but when I press the clutch to the floor the noise goes away. When my foot is off the clutch the noise comes back. It's been like this since I bought the car (I noticed it a few weeks after buying) I was hoping it was the clutch release bearing but I believe the opposite happens then.

So does anyone have a guestimation on how much it would cost for someone to change the input shaft bearing?

Is it a big job?

And, finally, would I need to change any other bearings or anything else? Would you recommend changing the clutch as well?

Cheers guys
 
I'm getting a little confused really, as some are saying the clutch release bearing and others are saying it's the input shaft bearing.

I've read that if it's a rattly noise when your foot is not on the clutch but goes away when you have your foot on the clutch it's input shaft bearing (this is the issue I have)
But I've heard that if the noise is when your foot is on the clutch but goes away when you release the clutch it's release bearing.

But then people are saying the opposite too, which is correct? Confused.com

If it was the input shaft bearing how much roughly would I be looking at? and would it be worth changing anything else? How big a job is it?
 
Not sure, you'd have to get a quote from a garage. I'd still wager it being the release bearing, it's a common issue on a clutch that needs replacing.
 
Thanks for your help I will, I was considering changing the clutch because I thought it could be the release bearing so I priced a clutch but I'll try and get a quote to do both. It'll be easier to do them both at the same time.

Has anyone had this done? And what did you pay?
 
If the noise can be heard at idle, but goes away when you push the clutch, then it's gear box bearings.
If the noise is only heard when the clutch is pressed, then its a release bearing.
I wouldn't bother getting it looked at until it's quite loud as gear box bearings can make a row for a long time before they get worse.

Yeah that is what is happening, it is annoying as I hate noises and I know it's there. The car changes gear fine but seems your a mechanic is it a big job? and how much would I roughly pay to get it done?
 
The gearbox would have to come out, and be sent to a specialist. So i'll try my best to break the job down for you:

Remove and refit gearbox: labour at roughly £30 per hour for aprox 7 hours (Depends who you get to do it, could be as cheap as £20 per hour or main dealer at £130 per hour)
Gearbox bearings: specialist should be around £350-£400 max for bearings and seals.
Gearbox oil: A rough guess at £30 (Very rough guess)

You're now looking at an estimate of £600 - £700

Now as you're mechanic has the gearbox out, it'd be well recommended to fit a clutch unless your cars very low milage and that would probably add around £150

However the bearings SHOULD get a lot noisier before they became dangerous.

The best thing you can do is google 'gearbox specialist' or gearbox refurb' in your area, and get an expert opinion.

I hope this has helped you. I tend to ramble a bit.

Can you describe the type of noise your car is making, or even put a vid up of it? If you take it above idle in neutral, can you still hear it?
 
Thanks you have been helpful, basically the noise is like a rattly kind of noise which sounds like it comes from around where the gearbox is, if your in the driving seat it sounds like its coming more from passenger side. It's not really loud but enough to notice as soon as you press the clutch the rattly noise goes away. If you take it above idle you can still hear it upto around 2.5-3k then the engine sound takes over. But as said as soon as the clutch is pressed the noise completely goes away.
 
I had a rattle too and it was solved with a new clutch. Could be the springs coming loose on the clutch or as already said the release bearing
Do you find it hard to change gear in v-tec?

Sorry but this is wrong.

If the noise is heard when the clutch is not pressed, and it goes away when it is pressed then it is the clutch release bearing.
 
Ha I might just get a DC5 box fully refurbed and chuck that in there :lol:.

Right I'll try the cheapest option first that is probably changing the clutch and release bearing, would I be right in saying a genuine Honda clutch is around £160 ish?

Then if the noise persists I will then look into input shaft bearing. A few expensive months for me, valve clearances and service then clutch.

This is what mine is like as well. If you hold the revs at around 2k - 3k it makes a rattling noise. Even in neutral. As soon as you get higher in the rev range it goes away. Also the gearbox makes funny noises when in 2nd, 3rd and 4th low down the rev range. I cant describe the sound but its like a chugging sound, if that makes any sense. Press the clutch and all the noises go away.

I hope the gearbox is not on its way out. As MilanoChris has said it sounds clutch related. My car is on about 60,000 miles but has had 5 previous owners so I don't know how it has been driven.

I am going to TGM on the 15th August for FRSU I will have a chat with Tom and see what he reckons it is. Fingers crossed it wont be a gearbox overhaul job.

Oh and sometimes I'm finding it hard to change gear in VTEC so I think the clutch is on it's way out.
 
Yeah gearbox bearings shoonk. They'll get louder over time, but will need doing in the long run.

And no sorry craig won't be the release bearing if the noise stops when the clutch is pressed. The release bearing only starts spinning when the clutch is pressed, so basically it'd be the other way round. Springs would give a rattling noise not a bearing 'whirl'. Very hard to tell without hearing first hand.
 
So all of the people who had these symptoms and once they had their clutch change, their release bearing was found to be faulty, they are wrong? Okay then. :lol:
 
I'll try the clutch first as it is the cheaper option (I think). Rough estimate of labour charges to do the clutch? (Not sure if I've asked this before seems like dejavu).

Have you ever had a release bearing problem before?
