Yes the particles, the carrier movement sometime in the last 5k miles and the 122k miles of use have all affected the gears. I will check gear pattern with compound and adjust as needed. This should eliminate most all noise. We shall see!!
I have a full shim kit for carrier and pinion but will start with original setting. The visible pattern in the ring gears teeth is centered and no scoring, scratch marks, pits, etc.
Fingers are crossed!!
