I just installed one 2 days ago and it's definately more solid. I just took it out and would randomly turn, safely of course, and the response was terrific. But it makes a sound when I turn.
The noise is coming from the tops of the struts rubbing against the bar's endplates. Easy solution to that: get some lithium grease in a tube and spread it on the undersides of the endplates. You'll see there's a center section on them that's indented and has ridges. Just put the grease all over that area, leaving a thin film. You can also grease the sides of the strut tops, since that's what rubs against the endplates (rubber bushings in them expand and rub).
