Differential Contact Pattern At 500 Miles

I tried different shims in .002 increments. its a little noisy, but not nearly as noisy as I would expect with a sheisty pattern like that. what's killing me is no matter what shim pack I setup, that's the pattern I got. it just changed position on the tooth. I left it at .032, because it was at the best position toe-heel wise. there was a .072 shim between the inner race and the case itself, but I didn't have enough shims to run without it. what I failed to mention was that with no shims between the pinion and the bearing, the pattern was absolutely horrid. thanks for the responses. question now is, would it be worth my time to take it back apart and try this all again? and if not, should I bite the bullet and get a higher quality gear set and start over? or should I just run them?
