Whaaat?
If there is any "fun" in repacking bearings, it's in the cleaning and blowing them dry.
No, I have never "wound them right up to warp factor 7" ... always have used a bit of drag to keep the speed down.
Right or wrong, it's never caused any trouble, and bearings were always replaced if there were ANY visible defects in either the cone or the cup.
For that matter, then ... IF my car was in a shop, and if economics only allow time for a "greasy inspection", I'd just instruct them to replace them all.
The world has gotten WAY carried away with "numbers", "productivity", and "efficiency".
