When you take your gear diff apart, you will find a thin washer between the gear case and the bevel gear and on the other side between the bevel gear and the gear case cover. Just add another washer or shim to each side. If you are still confused, go to step one in the manual. If you don't have a manual, you can download it from the Tamiya website.
