moog ball joints

I have Moog upper ball joints, car's nowhere near being on the road but when it is I'm wondering if there would be ANY indication so I can keep an eye out for this type failure. I suppose if the shaft shears I wouldn't see that without an NDI inspection, but maybe I'd feel slop. I dunno, that's crappy. I'd like to see some companies come back to the US, I'm hoping.
