Please help
I rebuilt my rear diff a few months ago using 501x halves, waiting for ceramic balls, but, built it, ran it, checked it, adjusted it etc.
Ran it for the 1st time on sunday, so thought i'd check it over, glad I did, balls are AGAIN starting to migrate through the pulley, 3rd one


.
WTF am I doing wrong, I've never had this problem, could it be the 5.5r bolted in, or am i just crap at adjusting this diff?
