Front driver's side "clunk"

[JABCAT]

Have a very noticeable "clunk" that appears to be coming from the front driver's side. 2003 Wrangler X with 156k mi. Here's everything that's been replaced with brand new components in the last couple months:

• Front & rear upper & lower control arms
• Front & rear sway bar bushings
• Front & rear sway bar end-links
• Front & rear shocks
• Front & rear springs
• Steering stabilizer
• Front track bar
• Front brakes (calipers, rotors, & pads)
• Wheels & tires

Took it to a well-respected off-road shop & they had it for 5 days. Said it was the nicest riding TJ they've had in the shop but couldn't identify the cause of the "clunking".

Coming out of my driveway (rolled curb) definitely hear it. Drive over railroad tracks & it sounds like the entire front end is going to fall off. Everything is torqued to spec. Jump up & down on the bumper, no noise, so it has to be suspension-related? At a loss.

Usually loose shock bolts. It doesn't make the noise when you bounce the bumper because you can't move it fast enough for the shock to unseat from the perch.

If the shock bolts are tight like you said then my next guess would be a worn ball joint.

Are they stock suspension parts?

I was guessing ball joints as well.

All bolts have been torqued & re-torqued, and re-torqued.
Springs are H&R,
Shocks - Rancho RS5000X,
End-links are Moog,
Bushings are Moog,
Steering drag link - Moog,
Steering tie rod end - Moog,
Upper & lower control arms -Crown Automotive
Steering stabilizer - Monroe Magnum

I have seen the transfer case shift linkage do that

The crossmember to the front of an automatic transmission is also notorious for noise-nutserts get stripped or get loose

And yet, it could still be a worn ball joint.

I found my clunk to be the axle bushings where the upper control arms bolt on
YMMV
