Re: 2003 Explorer issues!
A bad hub assembly can cause problems but I fear you'll need additional parts. I'm assuming it's a front wheel that's the problem, in which case it might need a new tie rod, perhaps another cv joint and maybe even a set of ball joints that help pivot the wheel when you turn it by the steering wheel. If a few of the steering components go that help keep the tire in line with the correct geometry the hub will fail as it's not designed to take added stress that the other components can take away, which is why it's leaning inwards. It'll be an expensive fix to do get everything sorted out properly. If anything else the hub that they installed might be salvageable, but will be the most expensive part to replace.
