First post here.

150K, car sat for several weeks. Now, it has a "whirring" noise from the right front at any speed that stops when turning right. I jacked up the front and listened while under power. No discernable noise from outside, but, clearly inside. Assuming its a vibration transmitted from the engine but unclear on what it could be? CV? Bearing?

Any suggestions??

it could be the bearings. And when when the car is up does not make the noise because no weight is on the bearing.
That might be.
