Why would you hammer the cog back on?
Honestly, it is pretty easy to check out wheel bearings. Especially in this so called information age. You guys need to give people more credit. Just because someone isn't an experience bike mechanic doesn't make them stupid. And the phrase "violate your warranty" is almost an abusive term used to make people think they need to get their stuff serviced by the company that sold it to them. Honoring a warranty is a hit or miss proposition even under the best of circumstances. Just fix your own bike.
