I agree, tighten as much as possible.
But for the life of me, sometimes they will grunt and groan almost to the annoying stage. I can't stand unnecessary noises(the BOSS says I'm anal).
I grease the balls that it attaches to but never the bar(that'll make it worthless). I have tried taking the bar out and scrubbing with steal wool and cleaning with degreaser and wiping it clean. Didn't help much.
But yes, tighten them up.
