Just follow the manual or read some other diff posts on here they explain how to build the diffs correctly....
Heres the image from the manual on building the diffs

2. I think I know what you mean about the thrust bearing. It should be inserted with the flat edge away from the center of the diff so that the head of the screw has the most surface area to grip onto the thrust bearing.
3. There is no need to put additional diff balls in the three extra holes in the pulley. Those holes are reserved for attaching a front one-way.
4. The Tamiya method for tightening the diff has been mentioned before in the forums. Tamiya shows this method with a slightly confusing diagram in the DB-01 build manual (shows the diff with two parts locking the arms - an arrow - and a "X" symbol). Basically you put two small allen keys between the slots in the diff arms, hold the diffs in your hand (grabbing the allen keys to lock the arms in place), then you try to rotate the pulley toward you. If you can rotate the pulley while the diff arms are locked in place, then it is too loose. Keep tightening the diff screw until you can no longer turn the pulley by force.. This is about perfect for your diffs. Overtightening can be bad, so stop once you can no longer turn the pulley, then insert the diffs into your DB-01.
Hope this helps.
