Thanks for the ideas all. This morning I checked a few things:
Took off track bar to inspect bushings. Didn't see any that were obviously bad:
I re installed bolts & torqued to spec.
Next, I checked sway bar links, and could not budge any with a wrench. It's hard to get a torque wrench in there without removing the whole assy.
On the sway bar links - on the passenger side link, it appears the PO replaced a flange nut with a regular nut and washer. Unsure if thatís an issue. Pics below:
I also checked lower shock mount bolts. They were good.
Then I had an idea to bounce all 4 corners to see if I could recreate the noise. I was able to recreate the spring creak on the passenger front & driver rear corners. I hadn't previously lubed the rear swaybar bushings, they seem easy enough to get to so i'll give that a try.

Factory bumper, but i do have a winch + winch mounting plate. The winch hook is secured to the factory tow hook, and doesn't have much play at all.
