Whenever an old post about replacement parts surfaces, I find it interesting how brands have changed over the years, usually for the worse.
Deeza, the crown jewel just a few years ago, seems to have most of their parts now made in Taiwan. An email to corporate confirms that there is no way to find the country origin before ordering. Are they bad parts? Probably not, but who knows?
Raybestos pro? Somewhat hard to find, at least in my area.
Beck & Arnley used to claim they were an OEM reseller. Now, by a wider margin, just a reseller.
Moog parts are still decent....if you stay away from their "R" line. Trouble is, most people order Moog on a price point, receive the "R" line, and then complain about the quality of the part.
I feel that Dorman hasn't dropped any further, but that's not really saying anything. (I actually bought a Dorman part awhile back that was a 100% Ford part, complete with the Ford part number. Exception, not the rule)
I can't comment on the demise of AcDelco because I normally don't buy their parts. One of the nearest brick-and-mortar stores near me is an AcDelco parts store, but he carries no inventory.
To me it's really scary that people have their whole family riding in a vehicle that has been fixed by buying the cheapest parts available locally, usually with junk made in China.
