Ok, Mudder, I went back and re-read his posts, and YES, he did say:

“So, when I talk about being in and out of gear, etc.  The vibration occurs when stationary and moving.”

 :bowdown: I missed that statement completely. :hammerhead:

So..that should eliminate chassis, driveshaft, diffs, wheels & tires.  :thumbs:

Did the vibration start suddenly or gradually?  How many miles has it been there? :inthedark:

I would look at the flywheel, clutch disc, and pressure plate.  How many miles on the clutch, pressure plate, pilot bearing, and throw-out bearing?

It could be the pilot bearing has disintegrated, allowing the tip of the tranny input shaft to move perpendicular to the crankshaft. :dunno:

Gnarls. :spin:
