i've got the same problem and i've also done just about as much as you. i just checked my drive shaft just now and it seems to be solid. ...btw, how do i know if the u joints or shaft itself is bad??

Wheel bearing?

Did you ever figure this out?

I did a google search and came up with this topic, havent posted here in ages.

But after doing a 5 bolt swap, new Q45 brakes and wheels I have this problem.

The wheel shakes from 55mph > 80mph and it shakes on and off, it basically shakes for 2 seconds, then nothing for 2 seconds.

The wheels/tires came brand new road force balanced and they shook from the get go. I replaced the front tires and had them rebalanced and the problem didnt go away. I replaced the front wheel bearings, checked the ball joints, tie rods and still shaking.

I've read about the centering spring a couple times now and Im trying to find someone who has actually replaced this. Im getting sick of taking $100 shots in the dark that arent fixing my problem!

Quick thought update...

I decided to go pull out the centering spring on the rack to see if it was flattened out or something and made an interesting discovery.

With the spring completely removed I can move the steering wheel back and forth the exact same distance that it vibrates under speed without the rack moving. The shaking looks to be directly related to the distance of play in the rack when this spring is removed, which might suggest the tension is too loose and it allowing a miniscule amount of poor balance to effect steering.
