First post, as I found this forum while looking for info on my Taco. Getting it ready for a back and forth across the USA trip this summer. I've noticed some threads say to use a different viscosity gear oil between the front and rear diffs... Or is it just fine to put 75/90 in everything (both diffs, and transfer case)? I don't really do any heavy towing (just a snowmobile a few miles in the winter and that's about it), and no serious off roading....just 4x4 in the snow.
It's an 04
Thanks in advance!
