I was doing some speed runs and went from AWD to RWD. I was thinking it was a blown front diff because if I spin one wheel, the other one spins the same direction... which is not normal for an open diff. @LicketySplit and others said the grub screw from the on the diff cup may have let go and if there is nothing holding the pinion it's normal.
So I pulled it apart and found the grub screw intact, but the inside are now outside.
That is the pinion bearing (AR610019), outside the case. The input shaft/pinion (AR310468) does wiggle about, but if I stop it from moving the diff operates correctly.
Just to check the grub screw, which was very tight, i reseated it and it looks like about the same depth as before.
I can probably clean it up and push the bearing back in, but I' wondering why it's all wonky and thinking I spun the bearing in the housing (AR310854). Which means at least the housing toast and I need to do some major surgery.
Also why are there no shims between the diff cup and the bearing? Like duh Batman.
Thoughts?
A bit more data. I poked around inside the bearing seat and found some bits of the bearing. It looks like the outer seal and a snap ring?
