Perhaps a broken or weak spring in pressure plate
When your clutch makes a funny noise when you step on it, you might simply have sand in the mechanism. You can begin by cleaning the clutch. If this does not help, check the clutch slave cylinder to see if it is working properly as it tends to cause a squeaking sound when it is damaged.
A faulty fan clutch.
With just that to go on I would say that your clutch release bearing is going bad especially if the noise quits when you put pressure on the clutch
You probably have a "throwout bearing" going bad.
Hey Johnny==Sometines the clutch safety switch makes noise. GoodluckJoe
There may be some drag on the AC clutch when it is disengaged as the clutch 'free-wheels' during this time. When you engage the AC ,the clutch 'locks up' and the noise disappears. If the noise gets worse you may need to replace the clutch, if it stays the same and it not very loud, I would not replace it.
* If it is stiff and making a crunching noise when going into gear it means the syncromesh (which is the cogs between gear cogs are worn), If it is making a whining noise in first gear it's a flywheel in the clutch, if it makes a whistling noise while travelling the clutch needs replacing, failing all that the gearbox needs grease or your elbow does.
That noise is coming from your throw out bearing mate, the bearing that engages the pressure plate of your clutch, many vehicles make the noise, I have seen vehicles with a knew clutch put in and it still makes the noise, id doesnt effect the performance and is too big a problem to worry about.
Probably the through out bearing.
Throwout bearings are permanently lubricated and as such do not have a grease fitting. If the bearing grinds when you press the clutch your throwout bearing is trashed. Since it only makes noise when your clutch is rattling around, it's just an annoyance. If it gets to the point where it makes noise when you press the clutch you need a clutch job.
The clutch is working fine. The problem could be as simple as a loose belt.
No, main bearing noise is a rumble Throw out/release bearing for the clutch will only be heard when the clutch pedal is depressed. If you hear the noise without the clutch pedal being depressed, it is most likely the gearbox first motion shaft bearing that is at fault. First motion shaft bearing noise usually goes away when the clutch pedal is pressed.
