I've posted about this in my build somewhat recently - having the exact same issue.
Narrowed it down, with certainty, to the adjustable end of the trackbar. When the jamnut loosens the threaded rod moves and "pops" where it interfaces with the reemed end of the rod. Called Rusty's and asked if this is something they've had customers bring to them and/or is it common. Turns out it is common and was told to back the jamnut out a ways and use some red locktite on the threads, then torque the jamnut back down.
I had pulled the passenger side of the trackbar a couple weeks ago and cranked the jamnut down which resolved the pop for about a week - but it came back. This is when I called Rusty's. My plan is to fully pull the trackbar in order to locktite it and crank it down best. I don't recall reading anywhere to locktite it on initial install and have been running it for around a year with a couple good hard wheeling trips and a fair amount of heavy towing. Just became an issue this winter (brutally cold this year) and I had chalked it up to the cold. Rusty's told me it is not uncommon to have this happen because the lateral loads the Jeep puts on it are constantly trying to loosen the jamnut.
Hopefully within the week I'll pull it, locktite it, and see if it returns.
