2015 Tahoe right side front end shake at 80 mph

[mics]

OP, did you get this resolved? I have a 2017 Yukon that has the exact same thing. I can feel it coming from what I think is front right (pass). I swapped out wheels and tires and it definitely helped a lot, but it's still there. I'm just shy of 70k miles on mine, so I'm going to replace the wheel bearings and the CV axles to see if that helps. I wanted to wait until the Powerstop brake kit came in, but alas, Zoro cancelled my order so I have to reorder (probably from Amazon). The issue comes and goes in severity, so I'm thinking it's most likely wheel bearings.
