Constant hum from engine bay - diagnosis?

'95 9000 V6 3.0L CSE
I have a hum/growl I can't diagnose that has developed in the last few months and which comes from the engine bay - maybe the right hand side (opposite from auto tranny).
The hum relates to car speed. It increases with increasing car speed and goes to nothing when the car stops. It doesn't change when the gearbox shifts.
It does get slightly worse when turning to the left, but is still there when driving straight.
I'm told a drive shaft would likely "click". Suspension seems fine. Exhaust is fully intact. Car brakes well and in a straight line and is very Saab 9000 stable at all speeds including high motorway speeds.
Worried it could be the tranny. Have a squeak at idle which I think is water pump. Could it be the water pump getting worse?
Just can't get it. Any ideas?
