Whats up guys, got a diff question for the experts on how to get these things dialed. I'm running the IRS diff with the lightened IRS rings. I sanded the rings to get them flat, and basically installed them with everything else stock, to break in a groove into the rings (I will be using ceramic balls and wanted to get them a little more grip on the rings) However, with the stock stuff I had a major high spot in the diff.

I'm going to be changing out everything that I used however, I bought Boca ceramic bearings and diff balls, PRS gear, and a Slapmaster thrust. Hopefully that stuff will take care of the high spot I had, but I'm just wondering if there is anything I should check for that is known to create a tight spot on the diff action?
