The wheel will fall off. It fell off, it fell the fuck off, now its Ron Whites big fn building! LOL.
Seriously though, if its a hub, it can come apart and the wheel can fall off. When I was workin at the stealership, I had a truck come in late Friday afternoon. We would have to order a hub and it would have been there first thing Monday morning. Guy said he would bring it back, he didn't want to listen to us telling him that he really shouldn't be driving it. He circled the parking lot and decided he would catch a ride and leave the truck. I went ahead and pulled it in the shop to have it all tore down and waiting for the new one. When I started lifting it, all the weight came off of it, the wheel fell off with part of the hub attached. He wouldn't have made it home.
