Thanks for the advice on the above, I'm going to try to last out until the weather warms up and then replace the complete clutch.

The thrust bearing gets very noisier then starts to squeal all the time(thats what happened to mine) it wont just let go, it will tell you as it gets worse. Gearbox out I'm afraid to cure.

not disbuting your response, as i too think its the front input bearing, either that or output bearings on the t/box ( but they whine and hum mainly on overrun )
but you say the thrust bearing cannot fail, sorry to correct you but they can and do just fail.
as soon as you start to hear a whine off the bearing its not long before it siezes up and produces a squeel. the rapid heat build up soon starts to melt the plastic carrier which in turn pushes the bearing back and causes instant failure.
every single one that i have replaced ( and thats quite a few ) has done the same

Extreme 90.
Can you highlight in my posting where it says the thrust bearing cannot fail, as i believe all bearings will fail in time.
