We tried inserting 2 gears simultaneously, but nothing seems to go into place without potentially bending plastic. What are we missing?

I don't have any of the Vex differentials yet to play with, but I used to use the LEGO ones extensively. For those, I always inserted the center bevel gear first. Next, I would slide/rotate the two outer bevel gears into place (without the shafts), and when everything was lined up I would insert the shafts into the two outer bevel gears through the differential housing.
