the "old, dusty box", moog parts seem to still of the "moog quality of old", while the new, off-shore parts seem to be where the problems arise, especially the rubber parts.
when dust boots and bushings crack and fall apart 6 months or less after installation, then wear in movable joints follow soon after, those moog parts are junk in my opinion.
and has been said, there is definitely worse parts out there.
i have seen better quality "store brand" parts, and WAY WORSE garbage !
some applications and uses seem better than others, and it's to the point i can't honestly recommend any part these days unless i personally have experience with it.
that's just me.........
your mileage will vary.
