Took the family camping off grid in GW National Forest.

Did some trails there and explored the limits of the factory bumper approach angle.

And camped two nights—nice not to worry how loud the kids were being, which is a concern in campgrounds with other humans around....
On the interstate headed home: bang! Whap whap whap—initially thought we’d hit something in the road and gotten a flat. Pulled over and spent some time jacking up wheels, turning them, checking driveshafts etc. noise went away after driving (slowly) a total of about a mile to a gas station parking lot to diagnose. Drove around a quiet neighborhood—yup, still gone.
Got back on the highway and hit the brakes to allow folks to merge, only to have my wife ask way that noise was. I thought it was a car ahead of us accelerating but it turned out we had a vibration (like a very quiet jake brake) when braking or even in overrun, any time the wheels weren’t actively pulling the truck forward.
We limped home, staying off the interstate, and now I’m losing my mind trying to figure out what the bang was and what the vibration is, and whether they’re related....
The sound on overrun reminds me of my Volvo when I failed to properly torque a new tie rod end and it got progressively looser, so I’ve been thinking steering related stuff might be to blame.
I have checked rack (some movement in the bushings but nothing crazy and no clunk), ball joints, inner and outer tie rod ends, wheel bearings, axle shaft half snap rings—nothing seems obviously loose, although there’s definitely some play in the rack but I confirmed by pulling back the boot and asking my long suffering wife tomove the wheel that it’s not the inner TRE, as I’d suspected.
Any thoughts??? Arrrgh.
