chewed up dana 44 front

[barrolde]

Was not happy to pull my front diff cover and see this! I was almost done all the work I had planned too.

Obvious question is - is this normal wear and tear or abuse or a bad setup? The fluid was dirty but not low. I'd like to determine a potential cause so I know how to proceed, i dont want to just put another dana 44 in there if something is wrong w/ the setup and this will only happen again.

This is an open knuckle dana 44 right? but I'm not sure of the gearing yet, will count now. It is 4.10 on the 14 bolt cop rear diff.

Its passenger drop from my np205 and is turning 37" procomp's

The knuckle on the driver side axle reads 4358, the inner axle says spicer. The main diff gear reads 1 23 79 dana d 18520 b3r19 05-11

I guess I need to completely figure out what I have and then what to do... any suggestions?
