5,000mi '19 TRD Pro here. First 5,000 miles everything was butter. Since it got cold here in Chicago I've noticed what seems like front suspension clunking (less of a hard clunk and more of a rocking noise) driver and passenger sides at sub 10mph speeds, over speed bumps, potholes and angled inclines (driveways, uneven & bumpy corners).
Took the truck in for its 3000mi check-up last week. Mentioned to tech, and they assured me everything was tight, but they were unable to hear the noise.
My initial assumption was cold shocks or bushings, but when the noise was still there during a few days of above 60degrees, felt more to me like a sway bar, linkages, loose strut or control arm. I've done multiple gen1 Honda CRV lifts and felt every one of these loose parts at some point.
I did do a little cornfield driving down in Nashville on Garth Brook's Manager's farm. But nothing I'd be concerned with having caused an issue on a brand new truck.
I'll be searching for a solution as it seems like multiple people having something similar. Will take underbody video soon.
