Local Firestone's Hunter road force machine was down, since the was no wait, I let them check wheels with regular Hunter machine. I don't really suspect them as they are new Mercedes 8 hole types with new Continental extreme contact dws06, that were mounted and balanced at the dealer last year in spring. And, the issue was there with old, original factory wheels with new Micheline crossclimate+ tires. I do remember that for you it was the tires as the cause, and I will have mine roadforced after the car is back on the road, but my mind (likely foolishly) is bending towards bearings/hubs/brakes area. There's a 50% chance I'm right

I haven't done this yet, but all steering links and idler arm were done at the same time 3 years/30k mi ago. But I will, thanks for the pointer!
