Did some quick googling. Here is a link to a same vendor agreement from TRW citing ISO 9000, 9001, etc.:

Here is info on ISO and what it means for certified manufacturers:
http://globalpurchasing.com/counterf...nic-components
"Franchised distributors guarantee direct manufacturer traceability for all products, with pass-through warranties where needed, along with the best-in-class warehouse and process controls such as ISO 9001, ISO 14001 and ESD 20:20 certification. "
So, TRW can't just dump bad parts off on the gray market. They could lose their ISO cert for that, and in turn lose all their OE business with companies like BMW if they lost their cert.
Further searching, they are ISO 26262 certified, which covers safety of road going vehicles. They could get in deep poopy for dumping these control arms ANYWHERE if they were in fact somehow faulty.

Can we put this to rest now?
