I have been hearing a similar noise as you have described come from the right front when I drive over this one particular dip in the road near my house. I have also been experiencing a click and clunk through the steering wheel while turning at slow speeds especially when parking.
I finally pulled in the driveway about two weeks ago and had my wife available to turn the wheel left and right while it was doing it and found that the end of the drag link was moving in and out of the tube where it is swedged. I did a little digging and found a Star publication addressing this issue.
My truck spent the week at the dealer for them to open a Star case for the presence of the cab rattle after performing the TSB so I had them fix this as while it was there. I picked it up late last night and didn't feel the clicking and clunking through the steering wheel pulling into the driveway but haven't driven through the dip yet. I am hoping that is gone as well, it is worth having your dealer look at it regardless.
I can find the standalone doc, but not the source reference vehicle. Do you have a link?
