So I just ordered new rear endlinks, went with Moog of course. Got them out of the boxes and they're already greased and ready to go. Just have to insert the grease fittings which seem to be self tapping because they do not screw in easily. Not a big deal. What is a question of concern though is that one endlink is very solid as in I cannot freely move it. I believe, through years of replacing them, that this is considered normal and that they should be pretty stiff because opposite is bad. Well one is able to be moved freely, way too freely as I can spin both ends freely in all directions with ease. I'm guessing one is defective? It is definitely new but this makes me question using it or returning it to RockAuto. Thoughts?
