THERE is your problem, Using cheap ass brands like that are going to fail very quickly. When it comes to hubs, choose Timken, SKF, or Moog. Timken is very popular on this site and considered the best in bearings/hubs. I personally have run SKF and like them. SKF has an X-tracker ball bearing design which is nice. I hate Moog for valid reasons that I don't care to list because some members will probably get butthurt over but moog is ranked 3rd in my book because I would use it over cheapo brands
Edit: sorry for the re-post lol
