Steering wheel wobble at 65 mph+

My problem was in rear but... I had big o balance mine many times and they told me it's gotta be some other issue. Had it since I bought the truck. Thought it was in the driveline. Replaced carrier bearing.. nothing. Swapped tires all around.. nothing. Bought new rear falken tires.. nothing. Bought all new set of tires when the time came at discount tire. Looks as though they stripped ALL the weights and rebalanced. idk of that's what they always do but first time I noticed all new shiny weights on there. But my problem was fixed after that. Now Idk if it was the weights or the tires themselves.. But no more wobble. And they did it in a hurry. 20 min.s, right before close and I was outta there. And no issues since. So Idk if I just got the lucky draw with a tech who finally knew Wtf they were doing or what. But it had to be balancing.

 

I had wobbles after rotating my tires. I took it back to the Tire shop and the tech explained that once the truck and tires get to a certain speed there is some gyro type of energy created, and requires a "Harmonic Balancing" to fix.

It kinds made sense when he explained, and it did fix the problem.
