so this weekend i'ma change the oil in the rear dif, t-case. not doing the front dif as i checked it and it's color is still nice and clean looking, i know i spins all the time but under no load maybe kept it cleaner longer.

for the rear the manual calls for a synthetic 75-90, will the normal conventional, 80-90 be ok? i have a few gallons of this on the shelf.

the t-case calls for atf+4, however my 93 toyota calls for atf as well and i use 30 weight non detergent oil in it. would that be ok in the tcase on my dodge as it is in the toyota??

As for the transfer case you can use ATF+3. I've been doing that since brand new. No issues.

If it's limited slip then you are stuck to the synthetic 75w-90. As for open diff I've been running 85w-90 all these years no issues. 

You can run the regular 80-90 but if you tow heavy I would change it more often but like Mike said if its a limited slip I would definitely stick with the synthetic 75-90 as well..

As far as the t-case I would definitely stick with atf.
