If so how did you get the little black caps to stay on the back wheels? Im getting frustrated but want my stroller to be complete!
Thanks

you have to use a hammer. turn the stroller on its side and hammer the black part down. it should say that in the instructions. i dont have that exact one but i do have the graco passage in clarissa

I must be doing something wrong, the little cap just keeps rolling, but im going to keep trying thanks!
