Help with wheel bearing?

[tmorales509]

Hey guys so back in august i changed out my driver side wheel bearing. Only 3 months later and its making a really bad grinding sound again. So i took off the hub and spun it and it sounds bad again. I'm not sure why it went bad so fast idk if i did something wrong installing it maybe? Also the little rubber gasket thing around the bearing is really torn up to. I will put a picture up. Any reason why it would go out so fast or is it just bad luck with the new bearing. By the way they are ABI brand bearing and luckily i bought 2 of them because i was going to do both sides but just ended up doing the driver side since the passenger side is still good so i have a extra bearing. And i put a video of the sound.

Here's another pic of the bearing seal. I just notice that the wear on the seal is only on one side as you can see. Is that any indication of something?
