I imagine it wouldn't hurt if you put a couple turns on the center nut, but how did your anti-sway bar bushings look, specifically the links. You would have had to remove/replace them when you did your shock replacement. I did my shocks at 84,000 miles and all the bushings were shot. This could cause the noise you speak of. This is also the culprit of that ever so common rear creaking/cracking sound as well. I paid less than $100 for all bushings. Yours are as well. Shoot me a private email if you want the name of the place, for respect to this forum.
