I can loosen the screws and get rid of the binding, but I don't feel comfortable that the screws are tight enought to prevent problems when runnning it on the track. I called AE and Chris suggested running it in a little to free up the gears and diff case a little. It looks like that worked for at least one other person on this board, so I'll give it a try.
Check to make sure that the pinion bearings are seated fully in the diff cases. Leave the diffs assembled and pull on the CVD to seat the bearing fully. I pressed them in like I have on every other AE kit I have built and they still had a very tight/crunchy mesh between the diff and the pinion gears. I yanked on the CVD's and it seated another 2-3mm into the housing and freed up the diffs. The 8.2 housings have a much tighter fit for the bearings.
