Not sure this will help but I had a really bad vibration on the front right wheel and could not find the source. speed and slip angle were influencing the degree to which it could be felt. After a lot of searching, including the bearings we eventually found the front engine mount to be the culprit! replaced it and all vibrations were gone! In your case though my feeling goes towards the bearings...
Let us know when you pinpoint the cause!

The FRONT ENGINE MOUNT was the cause of your vibration felt through the STEERING? Now I'm really scratching my head!!

As stated, I have replaced the bearings, the hubs, the hub carriers- everything except the steering rack up front. Its going in for new rear meats, one more balance on all wheels, going back on the alignment rack, and we'll see if that fixes anything.

While its up on the lift, I'll have a look at the engine mount apparently.

Actually, I think we can rule out the front engine mount. I just ran out to get groceries, and while driving I threw the car into neutral, with no change in vibration. I'll see have a look at it on the lift.

Good for you! Yeah the vibration was mostly through the steering wheel and threw off everyone at the club that test drove the car while trying to help diagnose! Bearing was the most common suggestion... but wrong. I know how frustrating it is not to know what wrong and sympathize!

I had a similar problem a couple of months ago, driving in France. As soon as the speed picked up to around 75-80mph the steering wheel was visibly shaking. It disappeared after a 3 hour drive.

I think my problem was linked to the fact that the car is sitting around on the same contact patch on the tyre for days at a time and it had slightly deformed the tyre.

I think the long fast drive heated the tyre nicely and centrifugal force help to re-round it.
