Imo. Life is a crap shoot and you get what you get.. moog might be better on tursday and delphi on friday. Moog says USA and delphi says turkey. Aftermakety will never be as good as factory. But its all we have. I also dont buy warranty. Buy the best part you can. Imo. From left delphi has the grease nipple... moog is middle and facory (fully threaded) has the grease stains
