The housing doesn't fail. The bearings do. You should be using the best parts you can afford, and that means OEM bearings.
There's no guesswork with OEM, nobody asking
"Hey has anybody done business with Nissan? How's their quality? I don't want to be putting down $200 and then never hear from them and never get my part shipped..."
There are minor differences. Example the hub face on the Ichiba hubs is slightly thinner than the OEM hubs. Only reason I know is you can't use ARP wheel studs on the Ichiba. They press in just fine, but the taper after the knurl is too large and extends too far past the hub surface. My rotors wouldn't clear the taper. The rotor were then sitting on the taper on the studs, and not flush against the hub face. Not a major difference, but caused me 6 months worth of brake gremlins, and several hundred dollars in trouble shooting.
OEM so the way to go.
