I want to punch a brick wall this is the worst thread ever.
Your bearings are punched in, they're like 2-3 dollar bearings at any reputable dealer, you need 8 of them. If you just ordered 4 of the same wheel you've got a problem because you have no drive wheel.
Toystory, there is a good reason you don't feel the pain of a problem because there is no huge problem.
The bearings in your rim halves only need to be tapped in.
THIS IS A CHEAP PRICE
Graingers is a specialty store, very good at what they do but cost a bit much on this item.
Also, a video based on replacing bearings in a 4 wheeler is a bit much for this situation.
