update NEW CULPRIT for me
Driveshaft place said yoke is perfect, U-joints are shot. Called Merlin, got both u-joints ordered for the rear driveshaft, but wouldn't you know it each u-joint is a different size and 1 is back ordered :) So I need to figure out which other size I need and order that one from Indy4x, because the driveshaft shop has my rear drivesahft and only 1 of the new u-joints.
ALSO:
Looking through the Vehicross Manual and found out that our FRONT PROPELLER (DRIVESHAFT) has CV's much like our front axles and if these go out it can cause driveline shaking. SO I crawled under there and BOTH of my CV's on the FRONT driveshaft are shot and look like they have been that way for a while, the joint is dry and does not look good at all. Looks like after I get new U-joints for the rear I will be having the front driveshaft (or front propeller as the manual calls it) rebuilt. Any suggestions on how to do this or who to go to? Think the same place could rebuild it? Also manual says if shaking is happening to try and reposition the front driveshaft (propeller) to different holes on the front (diff) side when reinstalling allen bolts. I will try that after rebuilding the CV's on the front driveshaft (propeller).
For more info if you have the Vehicross Service manual just do a search for "front propeller shaft" and you will see what I mean.
