Autozone or Napa Echlin, Quality?

I know I'm late to this discussion but I just joined this group and saw the bearing comments. I work for Timken and I can tell you that the "Made in USA" is deceptive when it's on their product. All it means is Assembled in the US. They get their components from all over the world, ship them here and put them together, then call it Made In USA. They avoid tariffs and can label the parts differently. The bearing plants that made the best bearings in the world were closed over the last 6 years because they had Union employees and the Timken Company hates the Union.
I have a friend who rebuilds semi transmissions and he said that over the last 10 years his expected mileage from a rebuild has gone from about 300K miles to about 175K. He uses the same Timken parts in the same color boxes with the same part numbers. When they went to non US manufactured components they loosened up the tolerances because they couldn't make them the way we did here in Canton, Ohio. So much for quality and truth.
Buy where you get the best price, more than likely the parts in the box are pretty much the same all over.
