I assume most folks here are using synthetic 75w-140 gear lube in the axles, especially the rear. What about the front?
The literature I have seen (owners manual, FSM) seem to indicate that 80w-90 is OK for the front. However, both front and rear diffs have 75w-140 synthetic on the metal tags, so that is what I used last time.
Anybody using 80w-90 or 75w-90 in the front? Or the rear for that matter, although I'm pretty sure I'll stick with the thick stuff for it.
I happen to wheel in a lot of MUD...Yep New Jersey sucks. I have found the Walmart brand 75W-140 synthetic to be a good choice for anual fluid changes. This gear lube is half the price of your name brands. BR:
