shake when you start to fan Alfa 155

I have an Alfa 155, that the thrust bearing, the clutch disc And these are in good condition, any suggestion ??? thank you

Hello partner, did the engine steering wheel rectified well? Because it is a typical alabeo fault of the steering wheel, it may have hard points and it is not very flat, in that case you have to rectify it with a good stone or change it, tell us to discover, a hug.

UPS, check it and was well spent with the stone, but it was made with rotating stone, I think the ideal is by turner, that is to say that the lathe spends it and left it as the well -smooth and bright brake discs, since when I remove the plate from the steering wheel I am stepped and without brightness, I believed that it is normal that seen that others that others were rectified, give me a light. It is expensive and tedious, since they have an infinity of connectors and always something is badly connected

The problem is the safest in the plane of that steering wheel is the insured failure.
