Moog - I've lost confidence

Not in a mopar, but 3/4 moog ball joints failed inspection after a year. Regular service and all highway driving.
Replaced under lifetime warranty. Funny, truck has 550,000 km's on it and two of them were original when i replaced all 4.
Trw is not available here, would use them.
Mainly using mevotech now as the quality is improving.
