Squeaking sound when clutch is engaged

[Bstock]

Weird issue recently. When driving I have a slight squeal. When I depress the clutch it goes away. When I show down with the gears it speaks very loudly.

I had my fly wheel refinished 4 years ago and new clutch kit.

I assumed my throw out beating was the culprit so I just bought a whole new kit. I replaced my 4 year old clutch with a new kit. Low and behold the squeak is still there. I have no idea what else it could be at this point.

Release bearings (throw out) are not in use when driving only when the clutch is depressed.

 

 

I would immediately check the oil level in the transmission.

Thanks for the quick reply. I did also drain the old oil, which came out beautiful and golden still. I was using 80-90 redline. Also refilled it till it came out of the fill plug.

Unlikely the transmission or clutch assembly now.

 

Inspect the U joints, specially the front one. They are pressed in on my '76 and had to replace the whole thing. A drive line shop can probably grind away the staking and fit new ones, I don't know the procedure for holding them in place.

Ah, maybe so! I never considered the u joint. I'll try to call around today. Thanks for the ideas Mike!
