'97 940 2.3 LPT, manual.

I've started no notice a bit of a howling and vibration felt through the pedals while driving at speeds around 30mph+. Its really intermittent, and steering in either slight direction stops it for a while before it returns. It happens independently of revs, or whether the clutch is disengaged.

My first thoughts were a front wheel bearing, the car's done 250k, but it also occurred to me that maybe its the propshaft bearing, and when I steer, the entire drivetrain is moving a little with out worn bushes. Obviously I don't want to induce any vibrations.

Any thoughts about how to pinpoint the issue? I've tried to get a video of it, but the microphone doesn't pick it up over the road/wind noise.
