Maybe death wobble??

I have a 2020 gasser with 47k miles. When around speeds 44-48 and 75-78 I feel a shimmer in the truck. Almost like when the you need brakes or the tires are out of balance. Not sure if it’s the death wobble. The steering wheel doesn’t shake during this and it’s not terrible. Anyone else have this? Ideas before I take it in and they tell me it’s nothing.

If it was death wobble you'd know it, and 100% feel it in the steering wheel. Death wobble is the entire front suspension and steering components oscillating uncontrollably.

Do you see any uneven tread wear on the tires? Is the truck lifted / larger tires?

I'd start with having the tires rotated and rebalanced. Then having the front end shaken down and alignment checked.

That’s what I thought after reading about it for a while.
No lifted or larger tires
That’s what I thought at first, I have felt it though on 2 different sets of tires. I go back through that process though

Tire balance. That's why it happens at certain speeds.

Death wobble is not a thing on these newer models. Probably the tires. I have had new tires do that, and at those speeds.
