Little update to this, Pulled the zerk on the slip joint and very small amount of grease came out under its own power.... So pulled the front drive shaft and went for a spin with with the CDL, smooth as could be so at least got it narrowed down to the front shaft..... A closer inspection reveals that one of the c clips on the front Ujoint was missing. So back to the shop, where they find a clip that would work and reballance it with even more washers tacked on to it 5 or 6 and good sized ones at that.... Its then I finally noticed that front shaft was in phase, and had an argument with someone thats never seen a DS set up out of phase in 40 years.
Went and procured the FSM information pertaining to the the correct orientation of the front shaft on a FZJ80 and had them do it again, JUST MAKE IT LOOK LIKE THE PICTURE dammit... Get it back and there is just 2 little weights on it to balance now huh...... Got it back under the truck and all is well smooth as you would expect for new U-joints. All in all they did a good job, and happy with the results, the phasing may have been like that since I bought it, as I have been under the impression the drive line is still all oem but it might have been in phase when I pulled it since my index marks line up with it being like that, and I just didnt notice it.
