Clutch sounds - squeeking and a boink.

[Okami]

Hey guys,

After renewing alot of stuff on my Hachi I still have a question regarding a new renewing project...

I have a clunk noise when for instance putting my foot on the clutch pedal and shift you hear a kaboink somewhere underneath me...

its hard to explain but also when I press the clutch pedal I hear a squeek so I think (and my mechanic friend also thinks) that I probably need to fix the Clutch Slave Cylinder...

What do you guys think...

Also when having the car in neutral or just gassing on the motorway and looking at the clutch STICK I see some heavy vibration... is that normal?
I guess it might be since its an old car.

Plz let me know - thanks in advance.
