Mike,
I assume you are referring to the primary pinion attached to the driveline? The primary pinion bearings appear to be fine. I removed the pinion a few days ago and inspected it. Or are you referring to the differential pinions? I plan to remove the differential assy tomorrow and inspect the differential assy. Apologize if I'm asking silly questions, but I am a novice working on differentials.
Anther strange thing is the ring gear at the root-heel (very outside edge of the ring gear) gives an appearance like the pinion is meshed too tight; the edge of ring gear has slightly splinterd edges. I expected the pinion to be too close to the ring gear; meshing too close/deep, but the mesh patterns in the photos do not indicate that.
