2015 Expedition - Random Front End Vibration
Every once in a while, but only while under power and not coasting, I get a vibration from what feels like the front right. I lasts only about a second or two, then goes away. It is more noticeable at higher speeds, but it does happen in all gears and at all speeds. it feels like running over very small rumble strips. I've tried changing the active suspension to different settings, and that doesn't change anything. Truck has new tires that are balanced, new brakes, and an alignment.
Any thoughts are appreciated.

I'm not familiar with torque converter shudder, but now that I've gone and read bit and watched a few YT videos, that could be it. Thanks for the nudge in a direction....

If it is repeatable and predictable, watch your tachometer when you feel it. If you see the tach start to drop a few hundred rpm when it is vibrating, then torque converter is where I would be looking. It will shudder when it starts to lock up and will stop shuddering when it is fully engaged. Usually takes about 1 to 1.5 seconds for it to fully engage.
