The alarm bells for me would have been the lack of any branding and the price.
Genuine would of course be ideal but a SKF, SNR or FAG unit would give me equal confidence.
Sub £50 for a bearing hub assembly is simply too cheap and probably only good to get a short term cheap fix before selling the car or passing an MOT.

I changed one on the ex's Mitsubishi Colt and even that was £90 for a car that's about half the weight of an XC90 and has no added stress of AWD.
