Ordered some Moog ball joints for my 280zx - when they came, one of them was perfect with the grease zerks and castellated nut and all the parts - made in Japan. The other was an impostor - made in Korea - no grease zerk - and it had a nylock nut. I emailed Rock about my displeasure, and they shipped me a replacement immediately! My new part came today and like the first, it is in perfect shape.

I have ordered from RockAuto many times before, and will continue to do so.

Now I just need to get to work!

The parts were defiantly both Moog? I know you can chose different manufactures on RA, that's another good thing about them. I use them all the time now. My truck front end is being built by RA.....From the Fender, front valance, and all new front suspension.
