massive creaking sounds from front end

[plumbcut]

A couple years ago I rebuilt a 4x4 pickup completely, from the ground up. The front end now creaks hellaciously whilst turning the steering wheel left to right (and back), especially at slow speeds like pulling into or out of a tight parking space.

Anyone ever experience something like this? The frame was powder coated and Im thinking its the rivets creaking where they have started to (surface) rust... I dont really want to bathe my truck in wd40 to see if its the culprit. The frame is pristine (no steering box cracks), has an AGR steering box, urethane body/spring/motor/swaybar/etc mounts EVERYWHERE, a steering box brace, the steering box has grade 8 studs that are TIGHT.

There is about 4 inches of lift, with the appropriate dropped steering arm. The front axle knuckles have new Dana ball joints upper & lower, and new tie rod ends everywhere.

If I sit under the front end while someone turns it, it doesnt really seem to come from a specific location, just sort of everywhere. Any advice? The truck started doing this a few months ago (not driven very often).. Maybe I will take a video w/ good sound of the truck.. My truck drives along the road *****in, and sounds like a tight truck. No squeaks, rattles, etc, until I make a tight slow turn and it creakkkks..... There sure is a lot of flex in the front end & frame on this old pickup, especially for having just medium sized tires and lift (4" and 33's)....
