I vote for a tire belt separation. Since it kicks in at a speed, that is the point where the centrifugal force distorts the tread section which is separating enough to make a serious out of balance condition.
I just had a front tire on one of my trucks act exactly the same way for the same reason. 3/4 ton truck with load E tires, only 6,000 miles on the set of tires.. Suddenly, death wobble kicked in at 40 MPH.. on a 9,000 lb truck [empty] If you look at the car, look for a bulge in the tread on one of the tires, front most likely. Setting, it might not be visually obvious, so look closely. On Sun, Mar 21, 2021 at 4:02 PM Scott Ritchey via Mercedes < mercedes@okiebenz.com> wrote: > Steering damper?
