This may be a silly post for some, but i searched the crap out of jeepforum, jeeps unlimited, dodge diesel sites etc and i have read that moog outsourced its suspension parts etc to other countries and that parts quailty suffered, and that raybestos was the way to go. I decided to take the plunge and ordered Moog upper and lower ball joints for my '04 WJ from rock auto. Im happy to report that i received 4 ball joints, all stamped 'made in the usa' and they look to be straight beefy. For anyone second guessing a moog purchase, i wouldn't. Raybestos may be improving, but i'll stick with Moog for now.
