My car needs a new front uj which I've found and got on order but I also need some oil for when it gets changed and whilst doing that I may Aswell do the diff and the transfer box do they all take 75w90 filly synthetic? If so how much and any recommendations on what's good?

correct atf (dex3) in both gearbox, and transfer Box. front diff is gl5 gearoil

it was a "mt75" gearbox oil made for them, but its not easy to find anymore. but have used atf dex 3 on them before

-diffs: gl5 80w90 (or gl 5 75w140 if hard use)
-transfer: use only atf dex3 or similar
-gearbox: mt75 oil if find, atf dex3, or you can use gl4 gearoil(not optimal, and can become "harder" to change gir when Cold), (even engineoil can be used... but dont remember the grade)
sorry about spelling errors and other crap from me... I am from noway... I dont know better
