Suspension Creaks on '21 Denali with Adaptive Ride Control

[tjonesdfw]

In the last several months, both the front and rear suspension on our '21 Sierra 1500 Denali 4wd with approximately 64,000 miles, have started popping/creaking.  I first started noticing a pop/creak at the front left when I step out of the truck and off the running board as the truck rebounds.  I weigh about 215lbs, and hardly ever tow or load the truck heavy, so its not like its ever getting an unusually heavy load.  Recently the right rear started making the same sound when stepping off the tailgate step or corner bumper steps.  Now, when driving at slow speeds, you can hear what sounds like the same creak coming from the front left suspension with any suspension movement.  Since it has Adaptive Ride Control, and with the sound coming from front AND rear, I wondered if the sound we're hearing could be coming from the ARC shocks failing?  I wouldn't think bushings front and rear would all be worn at 64K?
