Part number for what?

have you looked at the parts sticky at top of this FMTV forum?? "Parts spreadsheet"

Thanks for the help I think I have the correct part on the way now

As part of my drive-line upgrades leading up to the 3.07 gear swap , I did replace my front prop shaft with 4" unit I found at Eastern Surplus. (I still have the 3" if anyone needs a rebuild-able core.) My drive-line expert in Sparks re-balanced both my front and rear and replaced the splines on the rear at a very reasonable cost. This eliminated much of the vibration at highway speeds. The gear upgrade lowered the prop shaft speed considerably so it drives smooth as silk now..

not worth buying from military source...... it is nothing special.. just commercial truck parts... just go to a drive line shop that makes shafts for any big rig truck. The ujoints are standard Spicer heavyduty big rig Ujoints and the shafts are standard big rig tubes. 4" if I recall right.

with measurements they will make you a new one that is for sure better than NOS ..... for around same price... if not less since you won't have shipping to deal with.

I have one from my M1078 that had the D upgrade. Suitable for running or as a core for rebuilding. PM me or text to 775-901-3319. I am near Lake Tahoe.

Just thinking out loud here! I have not talked with my driveline shop yet.
Has anyone considered making up a two piece rear driveline with a center bearing?
I have not put a pencil to it yet, but the angles on my Ujoints measure roughly 8 degrees.
If the rear were tipped up 4 degrees it looks like the angles could be split among the 3 joints at about 4 degrees each.
My drivelines have new joints and balanced, still shitty.
I can't believe they built anything as poorly engineered as these thing are!

shimming the rear axle on LMTV to tilt it has bee discussed but not sure anyone but myself have done it. Overkill in my case since I also swapped to a high pinion (6x6) axle as my rear axle on my LMTV.
