Mine is obviously not lifted barely any....its just my OCD that has me actually turning OFF the stereo searching for noises.....so I guess I should be thankful its not as loud as you guys with the big big lifts!

Ask forgiveness, not permission.

the noise you folks are hearing is the loose slip yoke...
As driveline rotational speed increases, the loose fit parts start to swing in an egg-shapped motion...
Changing the Pinion angle will help, but you only need the adjustable upper link or lower links, (u don't need both, unless you just want them)...This really JUST helps the angle on the REAR u-joint, and does not help the actual driveline angle much at all, mabey less than 1 degree!!! (Although the splines would have a SLIGHT slip-depth davantage)
And you will STILL have the problem untill you replace the rear driveline....
I run 919 springs, which give almost 5" of lift... So my rear driveline angle is a noticeably steeper than stock.
Like I said, remove it for inspection and you'll see what I mean...
Your local driveline shop should be able to install a new slip yoke, on your driveline for a couple hundred....Make sure the new splines they use are At LEAST as long as the stock VX one...longer is betteras it allows more spline contact area....

Well I greased the driveshaft again this morning, ran my errands and the noise is almost totally gone, had to listen very hard to barely hear it......I am wondering if a seal has gone bad....I will see how long it is before it starts with the noise again.

Well I greased the driveshaft again this morning, had not greased since a couple months before Moab......ran my errands and the noise is almost totally gone, had to listen very hard to barely hear it (you guys probably wouldnt even hear it)......I am wondering if a seal has gone bad....I will see how long it is before it starts with the noise again.

You lubed the slip yoke, right? The grease just takes up the clearances on the worn out areas....makes em temporarly tighter and quieter....mine would run for a week or two and then the grease would just heat up and move outta the way a bit...makeing the worn slpined areas loose again...and then noise and vibratioin came back...
a bad seal could also be an issue here, but its too late for that now if you hear noises and vibrations

Alan, yes I greased u joints and slip yoke, but this morning driving it is making the grinding a tad....so its coming back......

Mine is getting so bad I am afraid it is going to break in half, I am not driving it again until I figure this out. So I don't need to buy another slip yoke they will be able to replace it with a non-Isuzu one?

Driveshaft place said yoke is perfect, U-joints are shot. Called Merlin, got one ordered from him, but it seems there are 2 different sizes on the rear driveshaft. So I need to figure out which other size I need and order that one from Indy4x.
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?
