I have a 2000 Chevy Blazer 4dr 4wd and I had the front passenger hub bearing go about 3 months ago and I had replaced it. Now the noise is back and it seemed it was coming from the drivers front so i replaced that and no good. Whats the chance of have a defective passenger hub bearing? It has a 1 year warranty. I don't want to have to go through taking it out and doing a guessing game. If I have to replace it again will under the warranty but is there any way to test it or is there other problems possibly?

 

I'm on my second passenger side hub bearing in a year. So I would say your chances of it failing is pretty good.
