I will be rebuilding my hubs soon and i am wondering what viscosity oil to use in the diffs/TC. I have heard that some of you use the same oil in the TC as in the diffs. I will be putting some expensive fully synthetic toyota oil in the manual gearbox as i have read on the other forum that this was the only oil that cured the sticky/clunky gear shift.
User manual says:
75w90 for the gearbox and TC (gl4 or gl5)
90 above -18deg c and 80w90 or 80w below -18deg c for the diffs. (hypoid gl5)
If i were to use the same oil in both should i go for 75w90 or 80w90? It will have to be gl5 as diff can only take gl5.
