NV2410R Transfer Case Used Oil Analysis

[CarbonSteel]

I wanted to share the UOAs to date for my transfer case. Nothing stands out as a particular issue other than some shearing that occurred and resulted in a 17% decrease in viscosity in the last run and even that is not a big concern.

Wear metals (iron, aluminum, and copper) continue to drop on a per mile basis despite longer runs past the initial fill as should be expected. For the curious, I dumped it at 30K to set a baseline when I re-geared and ATF+4 is cheap enough so I will stick with a 25K fluid change going forward.

Enjoy!

Out of curiosity, how many miles would you estimate was spent in 4wd?

Somewhere between 500 and 700. Of course, there are always parts spinning in the transfer case even in 4x2 so there will always be wear metals present.

Is there a magnet on the drain plug like the transmission? It is always interesting to see how much ferrous metal is on that plug when doing a transmission service. On my wife's odyssey it is a bit concerning the first few times, you can give the drain plug a "spikey hair-do".

There is, but there is little more than metal "paste" that is collected. The first OC I did had a bit more, but nothing like the rear axle when I dumped it @ 5K miles. That plug had more than a spikey hairdo...it had curly twirlies as well.
