I just tore down my left knuckle on 1980 HJ45, and came across this damage on the Birfield joint. This is my first time doing this. Found that bearing that you see sitting on the top of birfield, buried in the grease in the bottom of the knuckle housing. The strange thing is,,,Where did it come from? None of the bearings that I remove are missing any pieces. Its bigger bearing than the upper and lower knuckle bearings. Is it what caused that scoring on the unit? Just left in the grease by PO when he replaced bearings? Was this damage from 30 years ago?
I guess my main question is,,,,If I tear down the birfield, and dont see any inner damage, does that scoring on the outside matter? For a newbie,,,at what point do you buy a new birfield? What am I looking for?
