Low pitched driveline noise

[lucky8926]

I’ve got some sort of low pitched howl or whine. It’s intermittent which makes me think it’s driveline related and I only notice it at lower speeds. It is very sporadic and doesn’t happen all the time. I’ve attached a video so you can hear it.

Just an update. It seems to only do it after I’ve been driving at highway speeds, but still only hear it at low speeds. So if I’ve been on the highway then come into town I’ll hear it when stopping at or taking off from stop signs or if I’m going slow in a parking lot.
also, about a year ago every once in while I would notice when I was going to work there’s a small incline and then a stop sign and then I would turn left it felt like the rear end was binding or grabbing just a little bit. It was very intermittent so I didn’t really think much about it.

I will tell you what a service advisor told me. Just drive the truck, I focus on the little noises and this guy said all vehicles make noise, enjoy the truck.

possibly a u-joint or the mid-shaft bearing on it's way out.
