After several happy months of absolute quiet with with our 2019 3LR, now have a creaking under. Am convinced it is coming from the mounting blocks of the sway-bars (anti-roll) which have dried out in the warmer, less humid conditions of our spring. They are well buried, not exposed like lesser vehicles', but may get some quietening(?) water-damping the next time we drive in the rain. Will access and dry lube them when able, and report back. Cheers.
...bonded to those bushings.(?) Are you sure? Goodness, that would be a first. The noise seems to be communicated through the chassis, a 'heavy' sound. Blocks are available which include a bonded teflon sleeve; is this what you have in mind?
