Now you are making progress. Always helps to have someone who knows what they are doing.
Do not replace the flywheel unless it is too far gone to surface, which it likely is not. Your tech will be able to tell you when he does the clutch job and can inspect.
Are you getting the grinding noise when she is pointed straight ahead or only in turns?
Agreed! Starting point is certainly finding the right tech with the right tools and willing to spend the time to answer the questions of a Ferrari "FNG".
Copy that on the Flywheel - he actually said the same thing - especially considering the cost.
As far as the noise...it is more of a pulsed sound rather than a continuous thing....and does change frequency depending on wheel rotation....so it is only occuring at certain points of a full 360 degree wheel spin...and only happens in the following conditions:
A: Right hand turns...either from a stop, or at speed but a sweeping right hand turn.
B: When the car is going straight, but is slightly inclined.....meaning Driver to Passenger side upsloped...causing increased load on Rear Drivers side wheel.
C: Braking from say 40 mph to stop/almost stopped.
At speed - going down highway 65-75MPH....no noise is occuring or is so slight it is un-noticable.
We took the wheel off, removed the pads, cleaned the rotor and other parts. Also - we grabbed the rotor and tried to move it...to indicate a bad bearing...but it was as solid as a rock. Turned the rotor by hand with wheel removed and could not duplicate the sound.
Have priced a new bearing from recambi - but very reluctant to click "purchase" because I really dont think it is a bearing issue.
Have not removed the axle boot and tried to grease it yet - only other option I can think of besides removing the hub and bearing to inspect.
