Can you recreate the vibration with the vehicle up on "Jack stands under the axle housings" for FREE WHEEL spin and proper "ride position"... spinning the wheels with load and "no load"... and with the assistance of a helper make observations that way from underneath?  Maybe see if just one axle does the vibration, or elewhere, like a drive shaft, or the tranny itself.

all the same and radial tires at that.  Im going to check all of the mounts etc. for loose nuts.  But it feels as if something is off balance but under load it's fine.

This may be a strange question, but.. Are all of the tires the same size and condition, or if not, might it be that when you take it off "load" and then power back the differences "translate" back thru the tires to the drivelines trying to "catch up" at different speeds or conditions (like balances, tread types, wear factors, alignment, etc)?

No big changes just getting it on the road for my first time.  The transfer case handles rattle some but there's something else going on when alifting off throttle and then back on with slight throttle the whole things vibrates

QUESTION... When did you start noticing it?  Was it after any major "changes", or "incidents" (like off roading)?  Pinion angle too extreme, bent drive shaft, worn gears in transmission or OD, etc.

Ok.  How about shifting out of OD into direct drive.  Same?  This is in 2WD, right?

That description also makes me wonder about your U joints.  Especially when you say it vibrates the whole jeep.  May be hard to twist by hand but another way is to jack up wheel and turn the tire back and forth.  Watch the yokes to see if there's movement between the yoke and driveshaft ( both - at the transfer and differential).  This works for front or back. Lifting both wheels on an axle will just get the other wheel spinning.

If you can rule out the U joints, there may be some other things to look at.

I was just stating I have an OD.  The shifters rattle but its like a whole tranny thing when I lift off throttle and then reapply it will vibrate whole jeep

How did you determine it was the OD?  Have you applied tension (forward/rear/side-to-side) to each shifter to see if the rattle changes?

Transmission question.  I have an overdrive on my 3 speed.  Works great.  However, when I am driving and I let off the gas it often shakes and rattles.  Is that a bad bearing?  Under throttle it's fine if a bit noisy.  I emptied and replaced the gear oil.

Looks purty.  Happy motoring.

I went through each wheel and readjusted the pads and while they were a bit off it wasn't enough to make a major change.  I got tired of crawling under it on hard concrete so I brought it to my local shop who works on classics and did a lot on my 61 Chevy apache.  In the meantime.  Pics of the jeep as it stands!  Getting the fold out windshield hardware powder coated.

Since my reference was brought up, let me try to clarify.  There is supposed to be a "vent hole" (pic 1 attached) in the original MC cap.  Sometimes via dirt or paint it gets covered up.  The remote reservoir should have a vent in it, being the "highest point".  If the original MC cap had a "working vent", the system would be able to suck air in, or release pressure slightly.  Hopefully the KW cap not only is threaded, but seals the MC.  The sequence of pics show the bottom deflector of the original cap, then the components of the cap, and the last the pieces of "my system set up".  I hope that helps.

Vintage Jeeper sells a cap with a threaded hole in the top in which you put a nipple and hose up to the remote reservoir.

This is how I've seen it described.  I just don't have any experience - but if no air gets in, it should work.
