Wheel bearing issues

[okcguy]

About 2 yrs ago I hit a short curb at a slow speed. I noticed a humming noise after that, which I attributed to a bad wheel bearing/hub. I recently decided to replace it as I felt the vibration was just slightly worse. I bought a new OEM hub off ebay. I installed it yesterday and it seems to have gotten worse. I get a pronounced hum at 54 mph. I went to the tire store for a rotation/balance and they recommended new tires as they're near their end. Ordered them and going back tomorrow for install. After that I'll try to schedule an alignment. What would the chances are of a defective hub out of the box? I'm tempted to buy an aftermarket hub and swap it out to rule out that out. What would you guys check next?

I have replaced three wheel bearings, but the noise that I had left with the bearing. I had some water get into my parking brake, rusting the drum and rubbing on the shoes. This made an annoying rumble. I replaced the drum/disc. I have not replaced a drive shaft or any CV joint.
Perhaps you could provide more details about the roar, and your curb damage. Could it have bent your disc splash shield or an under panel?
Humans tend to associate unrelated phenomena. This helps us make sense of things that don't make sense. Are you confident that this noise manifested immediately after your collision?
