? rear differential housing developing a weep or just cosmoline mixed wit sheep fat?

Spotted this recently ...
finally had a decent
opportunity to check the diff gear oil level
level is fine and gear oil looks clean and not black! Such as in these pictorials
I grabbed a finger of black slime and smelt it did not have the nasty gear oil odor

I did spray the black cosmoline product on the diff housing before the winter
And also leftover black woolWax residue from a couple winters ago

backstory...
project: deWeathering
most of it was sanded blasted to the silver metal about 5 years ago
then primered with eastWood paint
then the black WoolWax
and now the black Cosmoline which must heat up to liquidy and the wind tunnel under the truck blows it upward?
that is whut i am under the assumption of happening back there deep underneath

ROFLMAO.

I have yet to hear of a differential rusting through.

There are plentiful pics out there of gen1 taco diff covers rotting and leaking gear oil bad

I'm sure there are examples of any situation.

The reality is those examples are most often the extremes. To use statistics, beyond the +/- 3 sigma out in the tails of distribution.....or in the 0.1% of the population of owners.

Delete those that don't live the salt life and the number might increase exponentially

I can tell you there was a good percentage of gen1, and 2 taco frame's that rotted out.
Most of those trucks are already dead in the boneyard.

 

[JayQQ97]

Frames replaced then the rear diff cover rotts out

That is a prime way to skew the data and shade the results to support your theory. You must be running for office this November.
