Here we go, the pot calling the kettle black. No need to get so worked up about it, it fair to challenge statements that don't hold water, its nothing personal. I make mistakes all the time but I don't believe this is one of them.
A bearing that falls within new specs and has no damage to the soft overlay has not been damaged by particle matter regardless of which filter was used be it FU, Wix or 2 pieces of toilet paper and a paper towel. That cannot be so hard to accept of understand.
Anyway no point in beating dead horse, you can have the last word.
Edit: Z listen man I don't like hammering on people and I admit I am not very tactful, if I did I am genuinely sorry.
