Driveline noise/drone/vibration

Keep us posted!

Are you going to follow-up at all on the out of phase issue? It seems worthwhile since you've got the drive shaft out of the car.

Not at this point. If this doesn't cure it, I'll look into pinion angle and probably take the driveshaft over to a local driveshaft shop.

I'm running out of driving time though... Winter is coming and I need to get a few things done before it gets too cold.

Get the driveshaft rebuilt. My money’s on this.

My money was on the u-joints from the get-go.

I am just about to do the u-joints in my Imperial. The joints are very tight with no play, but off idle on up i get a woop woop with speed and a vibration at highway speeds above 65. I think it is also the Double Cardan CV Centering Yoke

That now seems to be out of stock every where I look suddenly.
