Johny used his already, so this problem would have showed before.

The problem is that they don't have got much play between the bearings that support the diff. Sometimes you don't use shims at all with those bulkless things.

And normally when a diff, which is designed like the bulkless, has problems like Johny discribes (binding when the screws are tightened) the problem is that the bearings get cought up. it wouldn't make sence that the pinion is touching the diff-case.
