Strange problem when braking...

[Stepahncro]

Hello to all!

I have strange problem when braking at speed above 50 km/h.

Sound I get is like some metal is grinding. Feels like in position of drive shaft.

On speed between 45 to 60 I can hear like bad bearing high humming noise. It is not very loud but I can hear it.

For input recently changed all 4 wheele bearings and all brakes are almost new.

Problem I first heard when I start to brake going downhill.

Any help and suggestion or someone had same issue and reparied it.

Thank you!

I am positive that sound is in drive shaft area but not sure if center bearing bad or something else.
