12L4 wheel question

i've got new wheels/tires for it. but the bearing can go in from one side and out the other. meaning even with the lock nut on, the wheel and slide in and out of the bearings easily.

is there an adapter i should be using ? stock wheels have a divider in it to stop the bearing from moving.

Thanks for the advice.

ar thats wht i am thinking.

u know where can i get and price ?

RCmart have ?

Thanks !
