Toyota Matrix Jack Problem

I just replaced the rear wheel bearing assembly on my AWD matrix. Three days later, it began making a grinding or rubbing noise, so jacked it up, and could get the tire to wiggle top to bottom - so the bearing assembly failed. My question - why would this assembly go bad so fast? did I do something wrong the first time? It wasnt a cheap part - was a timken from partsgeek. How do I tell if the jackshaft is bad, and could a bad jack shaft ruin its bearing that fast?

Symptom indicates the possibility of improper torquing of the central nut for the driveshaft, 159 ft.lbs.

The best way to ebnsure it is torqued correctly is to torque to specs, loosen nut, retorque and loosen 2 or 3 times to get the bearing cones to be seated correctly.
