How do these gears look?

Ok gents, here's a 10 bolt that I rebuilt in December 2016, 45k miles ago. Serviced it today (not the first oil swap its had).

Gears are Motive gear 4.10 with an Eaton Trutrac. No regrets on either purchase.

The truck drives fine. The rear end has a minor "hooooooooo" sound from 50-60 but it's done that since day 1 and I'm the only one that notices it.


I have a vibration at around 60 that I still think is an unbalanced tire (tire shop has balanced it twice and claims it's OK) but the vibration never happened prior to the tire swap.

So on the ring gear I did notice these unusual tiger stripes. Pics show everything after spraying down with brake cleaner, so the teeth look dry. Anyone see the tiger stripes? Look suspicious to anyone?

Oil looked fine, it was about 2 years old, still green. I did find a small amount of silver glitter in the bottom of the diff but not enough to "feel", just saw a little on my finger after dragging the bottom of the pumpkin

I did the same thing almost 2 years ago on my 97, 10 bolts. 373 gears though, from summit racing. Did the crush sleeve eliminator. Changed all my bearings and races at that time. Never any noise. If you've run it that far, chances are, your good. I have noticed with mine, that there is maybe a little more slack in the ring gear adjustment, but I was at about 6 thousands and spec was 4 to 8, so I should be good. I will pull the cover one day, and look.
