Not that technical but might be....

Oh well in that case I can definitely confirm it's something to do with the clutch then, numbnuts.

 

Yeah that really helps me (us) figure out a possible soolution. Thanks for that.

 

No offence but if you've got nothing worthwhile to say then I'd really rather you said nothing.

Be nice :hunter:

 

SoonTo had a point, if no-one has come forth with a "I know exactly what this problem is" solution then you're going to have to get your hands dirty. No need to go off on one.

Mate I wasn't going off on one, just don't really see the need in pointless posts like the one above. I don't mind getting my hands dirty I have no problems with that! Was just hoping someone would say something like "check this and do that then you'll know it's the so-and-so that needs whatever" you know?

 

Like I said, wasn't wanting a step by step guide, just a few guidelines as to what it could be - bearing mind I'm a novice with things like this and I have no idea where to start.

Ian (and soonto) make good points, so please keep it civil.

 

The clutch system is a pretty simple device so there's only a few parts which could cause a squeak. First off you should fully lubricate the pedal assembly inside the car. That will eliminate 90% of clutch noises.

 

If you still have an issue the next likely cause is the pivot the clutch fork sits on. I've never heard of this causing a problem before, but greasing it will require gearbox removal.

 

It may also be cause by a worn master or slave cylinder, but I'd have thought you'd see a loss of clutch fluid if these are at fault.

 

Here's a basic pic of the clutch system (shamelessly stolen from Terribleturner):

More than likely the clutch release bearing going on and off load.

 

Agreed, that could well be the cause. Unfortunately its yet another gearbox-out job.

 

Best to eliminate all others first (not that there are that many) hence the questions to clarify where the sound is coming from.

If you are not overly mechanically minded, then best not to try and take out your gearbox by yourself. It isn't an easy job at all, definitely easier to do if you have a 2 or 4 post ramp. I've done mine under small ramps before and I don't want to do it again.

 

You'd have to remove/disconnect the prop shaft, then get to all the fixings of the gearbox to loosen them, remove all bracing and gearstick, undo clutch lines and then undo the gearbox fixings. Then wiggle it out.
