For starters, take the bowling ball out of the front trunk...
You're probably going to have to do some detective work on this one. Just because something isn't "noticeable loose" doesn't meant it is torqued down properly. If the suspension feels tight it makes me think it's in the stabilizer bar (most noticeable when turning) or it's something loose in the trunk (maybe the battery tray or something has come loose underneath the plastic cover). Check for loose bolts at the rod ends and any mounting brackets/bushings. Make sure you torque the nuts to the proper settings.
The quick and dirty method is to take a rubber mallet and start tapping firmly on the suspension (with the front in the air) components and listen for an abnormal noise (everything should sound solid as a rock). This is how I found one of my stabilizer bar nuts had backed off at one of the links. I think if it was steering related you would have other very noticeable symptoms hence why I would focus on the suspension. Since it happens both in left and right turns I am leaning towards the primary component for transitioning weight for both turning directions (this of course is if you don't find the bowling ball).
