Changing gear oil in high humidity?

[OCDoiler]

Yowza...heard it was bad. Was the single can enough for the entire TC?

I've read on a couple T4R sites that a lot of owners are using the same 75w-80 as goes in the differentials....[/quote]

I sure hope so. The spec is 1.1quart (75w oil can is 1L). It did start to drip at the end. I tried to peak into the fill hole and couldn't verify the level, but know I got 99% in there and there was probably some residual left in there.
Yes, lots of folks use 75w90. Probably just fine in CA climate.

When we flood in the marsh I have driven through a half mile of moving water several times … After back home … with a clear plastic soda straw (perhaps I need to hide some) I take a sample … if not cloudy … rock on …

How are you gonna get the lube in the diff and transfer case?


I poured the oil out of the old school can into 2 regular plastic gear oil bottles. Then I fitted a 5/16 I.D. hose on the end, squeezed it in. Worked good and didn't require a pump.

Neat idea.

Don't let these guys get to you, this is a valid question. DOT 3/4 brake fluid is hygroscopic, but gear oil, ATF, motor oil are not. Even brake fluid doesn't absorb moisture that fast, anyway.

So THAT'S why getting coolant in your motor oil blows the head gasket!!
