'05 Ford Explorer vibration over 55 MPH

81,000 miles on it and starting last week I began to get a vibration at highway speeds. The vibration is both in the seats and the steering wheel, though it feels more so from the front end. HOWEVER, I already have had: both front lower ball joints replaced, the front axle replaced, the tires rotated AND aligned AND balanced, and a missing sway bar link replaced. I have no idea why it still vibrates. My mechanics (yes I tries 2 places) can’t get it right. Ideas???

Any status on the wheel bearings?

Find the frequency and speed and then you can relate it to something on the car…guessing sucks.

The vibration is pretty constant once at highway speed (above 55 or 60 MPH) and gets increasingly worse as I increase the speed. After driving more, it seems to be pretty prevalent from the passenger front wheel and the driver rear wheel, but I may be wrong.

Fantastic. Faulty/defective ball joint replacement. It allowed play side-side in the passenger front wheel. Only hundreds of dollars and weeks later…
