you may never get rid of polly noise even if you grease them "properly" w/ Right grease
Basically you put hype parts in car's suspension and take your chances what happens now or later.
Noise mainly comes from sides and inner tube as the polly try to act like bearings where it hits/rubs/rotates on the sides the car's "frame" and inner metal.
CA and sway bar(s) are famous noise headaches.Results?
A lot of times even the "polly" Grease come w/ them won't help depend on many things including how you clean all parts touching the polly.
More annoying, Can be just one to all of them making noise.So?
Some get noise at every bump now or down the road. Some of them replace w/ Moog etc "rubber" to stop this, If they keep the car.
Some get no noise but often doesn't = no problem and often ends up w/ CA and some others w/ a lot of play during driving.
Some get away w/ them for years and no noise.

Dr. Ian Malcolm: Yeah, but your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.
