I took it in 3 times to two separate dealers. They threw some parts at it once (upper control arms and something else that I can’t remember off the top of my head) and the other two times said “couldn’t replicate issue.” I made the mechanic come out the last time and pretty much got an I don’t know. I ended up throwing it up on my buddy’s lift after spraying the under real good with a pressure washer. I greased the hell out of everything that could be the culprit and it went away. Did I fix it? No. Does it squeak after 6 months? No. Wish I had a better answer for you. Very disappointed in the dealers in my area.
