"New upper ball joint" bad

XRF is out of China! Quality is low... Don't hesitate to use Moog, quality will be fine. I have used Moog for 40 years on every B body & A body made with no issues at all. Install them properly & grease them every 3500 miles & you should be fine. 90% of Moog is still made in the USA & the rest is out sourced. Is the old Mopar stuff outsourced? Probably but at least Moog monitors quality. The Moog box will say country of origin on the outside & really that doesn't matter if Moog (FM) monitors quality for Asia, Mexico ect. My 2 bits..Good luck with your project!

What Moog did 40 years ago has no relation at all to their parts today. 90% of all Moog stuff is made in the USA? You have their production numbers then? So let's see them. Because I can tell you all the Moog parts I've purchased recently are not USA made.

I still tend to think their quality is better than some of the other stuff out there for standard replacement parts, but I've gotten ball joints that didn't have the threads cut properly, a castle nut for a lower ball joint that had no threads at all, and other minor defects with Moog brand parts. Maybe I've just been unlucky, but I have definitely needed to return Moog parts because of quality control issues. I would still buy Moog parts, but, like I said earlier, I also plan on having to return parts when I buy them.
