A little tight but still can get in I think it would be ok (but pinions must all be installed first), but 3 of mine could not even get in (the bearing). If I did as you said, it woble badly, all three. I believe Goldfinger use a reamer to clear the tight space.
I think your problem with the pinions wobbling is due to the 5x10x4 bearing not sitting in the pinions properly.
I make sure that they go in right and flat by knocking it lightly in with a plastic tip hammer and a Hudy wheel nut wrench at the end on the bearing to press it in.
