I have a 2016 Trailhawk with the daystar lift and after about a month of ride I began to hear a squeaking noise coming from the right rear. I'm big on Jeeps, but not very mechanic-savvy so I had just assumed I had a defective shock or it needed grease. I took it in to the shop and it turned out one of the struts was rubbing against a skid plate. No idea how it got like this, but they were able to trim it an fix that awful noise. Not sure if this can relate to you but anything helps I guess.:crazyeyes:
