Hello all. I just received two brand-new Moog problem solver sway bar end links from Rock Auto. All four studs move freely with thumb pressure. I am almost certain the last time I replaced them I was unable to move the studs at all with my fingers and had to tap them with a rubber mallet to orient them to install. These are the problem solver end links with grease fittings. Am I correct to assume even though they've not been greased yet that it's unacceptable that I can move them with my fingers?
