Rumbling from NS, new bearing and driveshaft fitted

[Animesis]

Long time no see friends,
I did some work on the old girl recently, changed the front hubs and wheel bearings to brand new stuff from good old DMGRS (hence I'm pretty sure its not the wheel bearing)

On the first journey out after the work on the motorway a rumbling very similar to a wheel bearing appeared, I jacked the car up on the offending side, tyre off and had a listen with it spinning, definitely something on the passenger side between wheel and engine, couldnt pin point it anymore than that.

To imagine the sound, imagine rolling a brake disc along a concrete driveway (I've tested with the calliper off and the noise is still there)

As it has a new wheel bearing I've assumed it was the driveshaft and just replaced that this morning but the noise is still there.

To me its either the gearbox or a brand new wheel bearing is failing already?!

Any tips would be hugely appreciated
kindest regards and TIA
