Thrust washer Assembly Note

WARNING: This page is about a different car, the 2020 Mazda CX-30. However, it is still accessible from the selected car via links, so may be relevant.

Assemble the side gears, thrust washers and pinion gears to the gear case, then assemble the knock pin.
After assembling the knock pin, make a crimp so that the pin will not come out of the gear case.
Set a dial gauge to the pinion gear as indicated in the illustration.

If the backlash exceeds the standard, use the thrust washers to adjust.
