2013 Lariot SuperCrew 4WD
ISSUE: I can hear a humming noise with a very slight vibration in the steering wheel @45-55mph. As I decelerate you can hear the humming drop in noise level. If I'm on a long curve to the right, the noise gets louder but not when the steering wheel is turned to the left. At times, the steering column will squeak or hum while on that long right curve. Any one experience this or have an idea where I should start looking? It seems like a steering linkage, etc problem but I'm no mechanic and cannot afford the couple of hours of labor for a mechanic to research.

Tires are accurately balanced, wheel hub bearings are in good shape, wheel alignment is good,

 

Wheel bearing or poorly worn tire.

The steering unit tends to go bad with some loud screeching.

 

wheel bearings are good and even wear on the tires. I'll check into the steering unit. thx

 

Classic sign of a wheel bearing. How did you check for a bad one? If by the wiggle test, your bearing just about has to be totally gone before you can feel/see a bad one.
