On the Dodge Forums plus the 4 X 4 and off road forums that I belong too , the comments are that moog has switched to Mexico/China to manufacture there parts ( do a Google )
My parts store Car Quest dropped Moog do to too many problems and now offers Raybestos Professional Grade ( Dana/Spicer Chassis Parts ) what I use NOW .

Just did My Daughters Durango with the Raybestos Professional AKA / Spicer / NAPA Gold
" Replace with raybestos joints, they were originally Spicer/Dana named(but still manufactured by dana/spicer), but changed the name to "Raybestos" for dumb marketing strategies[1].
Spicer joints have many advantages campained to moogs, I like the fact they come with high grade hardware vs moog's low grade, they come painted with a rust resistant coating vs moog's bare metal coating, and most importantly they come with poly boots vs moog's rubber so you wont have any boot problems again! They seem better overall engineered geared more-so toward quality vs cost-analysis benefit ********. They are also used on many OEM high end vehicles. DANA and SPICER makes products for vehicles ranging from rear-ends to brakes, they've been around forever (ever hear of the :bow

and make good well engineered OEM products Vs federal mogul (federal mogul is purely aftermarket based company, makes MOOG " Moog also appears to be mfg. in Mexico / China now ?
