I went out and sort of inspected both sides. Everything looks to be fine...no clear point of contact issues and no cracks (that I could see). Hmmm.
Just in case you didn't know exactly where to look, when you sort of inspected both sides...
There are TWO of this arrangement per side. 2 bump stops on the D-side, and 2 on the P-Side.
They work in diagonally opposite pairs...so, on a turn to one side, ONE stop on THAT side hits, as well as its diagonally opposite stop on the OTHER side.
One of the OPPOSITE side's bump stops
So a turn to the driver's side is stopped by one D-side AND one P-side stop....and so forth.
Look at the contact points...hit them with some synthetic grease, and, then see if the noise persists.
The other common clunk area is the front sway bar. Look at the bar that runs along the front of the front cross member that is held by two brackets with bushings there...if those bushings are worn, you can get a clunk.
Also look at the ENDS of the sway bar, where they have links that come up from the LCA. The TOPS of those links tend to get worn, and, sometimes even get whittled off altogether...and, if worn enough, or worse, you get that type of clunk there too. (One sway bar end's link is shown in the above pic, coming up just to the left of the stop from the LCA)
A pic of a stock set-up:
BTW - The sway bar link in this picture is BROKEN, but, you can't tell in the pic, because when parked, the two separate pieces rest on each other, so, unless you look closely, you can't easily tell they are separated.
The tie rod ends and ball joints you already know to check.
