XB4 information about shimming the differential:
Please note that the XB4 was designed by purpose with a small play (clearance) on the gear mesh of the differential crown gear and pinion gear. This small play is made by purpose. You should not use any shims on the differential to eliminate this play. The differential during operation gets warmer and expands. In case the differential will not have a sufficient play the gears may not work smoothly, may lock or even break. For this reason it is suggested not to use any shims and to build the differential as per the instruction manual.
