When I change UP (not down seemingly) and very slightly mismatch the revs, there isa squeak/squeal as the clutch bites. If I change gear very gently it doesn't happen. And if I accelerate very hard it doesn't seem to happen either, although it could just be that it is very quick and I don't hear it.
Generally it pulls well, doesn;t judder etc.
So any ideas? Clutch plate? Thrust bearing? I read in another forum that WD40 might "do the trick" but I can't imagine what to do with the WD40 other than block my ears with it.
The car has done 40000 miles, much of which has been town and it's a 5 years old 1.6 petrol.
Thanks in advance for any thoughts,
