I've never heard one person have issues with Moog products. I know several people that work at Advance and they haven't had many returns on the Moog bearings.

Just because someone returns something and says it is defective, doesn't make it so. For instance, the exact game that Scotty has talked about probably occurs more than anything. You replace one bearing, but keep the box and receipt and when the other goes bad you remove the bad one and say it was the one you bought 8 months before that.
