Strange noise Alfa 147 3.2 GTA (see description)

I have this strange noise for over 6 months. Since I have this noise, I did 2 slalom races and 1 track day, and nothing has broken yet.
What do you think? Gearbox, clutch, drive shaft??
Thank's for help me about it!!

Wheel bearing.

@FedeBL4 thank's for your repport. Did you have the same kind of noise on other car, and it was the wheel bearing? Last week another track day (see video on my channel) and always this noise, but nothing has broken for the moment...

@nitro3398 I worked in an AR garage here in Italy, and i've seen a lot of worn wheel bearings making the same noise.

I suggest to have your GTA checked. If the problem is the bearing it should be detected instantly. Do you hear that noise when turning?

Anyway, the price of the bearing is around 100€ and, if you are able, you can change it yourself. Don't wait too much.

Take care of your great GTA!.

Let me now.

@FedeBL4 Hi, Since you advise me, we checked the front wheel bearings but unfortnetly it's not the cause (both are ok).

I have always the noise, someone else think that it's the cause of the external part of the drive shaft (axe notched in the wheel defekt).

And you do you think it could be this???

Thank's and best regards

@nitro3398 Did you check the semi-axle too?
