Very interesting reading there, particularly the comments section. Bottom line, Moog appears to have changed from manufacturing their own parts in USA, to reboxing from worldwide sources. They may rebox good stuff, or may rebox junk. They might still manufacture some of their own parts in the USA, but it sounds like that is becoming the exception instead of the rule. It was particularly discouraging to read of the one person who received a Meyle (!) part in a Moog box labeled "Made in USA"... second reply to comment # 8, dated Oct-2016:

The original order was for two tie-rods, the crap chinese one I returned was accompanied by a high quality Japanese part that also came in a Moog box marked “Made in USA”.
This is not only wrong, it’s illegal under US consumer protection laws.
The vendor responding to the comments on the page is clinging to the hope that any "Moog Engineer Approved" / "Moog Validated Construction" reboxed part must be ok, because it has the Moog name on it.
Be careful out there.
