I can’t create any wobble but seems odd to be able to see the spindle. If the wave washer compresses, won’t the spindle start fretting?
If you can't move the axle sideways, you probably have enough compression on the wave washer. It's there to apply preload to the bearings, you want enough but not too much. If you squash it completely flat, your bearings will wear faster.
It's inviting it straight back out again. Anything in the voids created by the waves will go no further because the next thing in the stack up is the bearing shield.
