OK, I just read the bearing part. Were they properly torqued in the two-step process or just tightened down like a gorilla? It makes a huge difference.

Cupping is generally caused by bad/weak shocks.

Bent a control arm maybe?
Really bad alignment?

My money is on alignment. How often do you have it checked?

Cupping is from the tires bouncing/vibrating. Shocks.

If it were an alignment problem, the wear would be relatively even around the tire.
