Oh good, something else Joe doesn't know anything about.
Joe, auto manufacturers have relied on outside sources for parts for decades. In some cases they may own part of the company that builds their parts, but not always.
Do you really think that in 1965 Ford build EVERY single piece of the Ford Mustang in house? They did not.
Actually, the reverse of what you believe is true, in the 80s auto manufactures started utilizing vertical integration which meant they started buying the companies that they were getting the various parts from .
In fact, having these companies and being able to sell them off is what kept Ford from having to take a bailout like GM and Chrysler did.
No kidding. Car builders have contracted out parts since the dawn of the auto industry! (Offhand, Model T carburetors and magnetos were contracted out, and companies have been buying Federal-Mogul engine bearings for over 100 years.)
I had a Jeep pickup...the engine was Jeep (AMC), but the transmission (Borg-Warner), transfer case (New Process), both axles (Dana), the steering gear, pump, and column (Saginaw), the alternator (Motorola), most of the interior switch-gear (Singer), the ignition system (Ford Duraspark), and the brake system (Bendix) were ALL outsourced! It is not new!
Trivia: which company (still around today) got its name from the grease-impregnated felt axle seals they were founded to supply for Model T's?
