Noise

Most common cause is a noisy front wheel bearing. You can verify that by raising that tire off the ground, then feeling for the vibration in the coil spring as you rotate the wheel by hand. Your mechanic will run the truck in gear on a hoist, then listen next to each bearing with a stethoscope.

Some designs will stop making noise when you turn toward the noisy bearing because some vehicle weight comes off of it. They can make more noise when turning away from the noisy side because more weight shifts onto that bearing. This can go on for years. I've only seen one that got so bad that the wheel was ready to fall off, and the owner refused to believe that was a problem! For most of us the annoyance gets to be too much after a few weeks.

This assumes I'm right about the bearing. You know I can't diagnose the cause over a computer. The best approach is to have it inspected at a tire and alignment shop, especially to rule out anything that could become a safety issue. The people there are experts at finding the causes of noises, vibrations, and bad tire wear.

The bearing assembly is bolted on. That makes the part considerably more expensive than the pressed-in design that Chrysler used in the '80s, but labor time is quite a bit less. If the parts aren't rusty and come apart easily, the bearing can be replaced in about an hour and no alignment is needed. The typical bearing costs around $150.00 for the part, give or take 50 bucks.
