Need help identifying sound

Little bit of background. My truck has 103k miles, and put less than 15k miles a year on my truck, mostly city. In the past 6 months I've had my 6" lift increased to 8"(don't think it's a factor but never know). Before that I had my head studs and EGr delete along with a few misc wear and tear stuff like hoses. I know the noise started before the lift, but can't remember of it was before the engine work. I think it might have started before.

To the noise. It's a deep growling(almost a grinding sound but not quite), and it only sounds when I'm turning left and accelerating at the same time. No sound when I turn right, and does not always sound when I turn left and I'm already at driving speed. But every time I'm turning left from a stop sign or light it makes the sound. I have also noticed that once the sound starts, if I punch the gas it will stop.

I know it is not my tires rubbing. Only thing I can figure is a pulley, possibly the power steering pulley, is going out. But I would think if it was the pulley it would make the sound turning either direction. Any help or ideas would be much appreciated.

May be a u-joint going bad on one of the front axles.... There are grease zreks on them, and I didn't know that for 50k miles until is started hearing noise from the front end during low speed hard turns to the left. Grease them up, and the sound went away

It would be nice if that was the issue, I actually just got my grease gun back from my dad this weekend. Any specific kind of grease it needs? if thats the problem, I hope I didnt ruin anything by driving on it for a few months.

I've heard of this before i think on another forum, they said their auto hubs were locked, and not supposed to be. check your hubs to see if one or both are locked in. other than that it could be bearings, jack it up and check the play.

I have also herd that it could be your exhaust pipe vibrating on the trans mount.... I had the same noise but I put my stacks on and straight pipe and also greased the he** out of the front end and it stopped

Made it by the mechanic this weekend and got the problem fixed. My exhaust was rubbing on the tranny or tranny mount. Mechanic loosened some bolts, and got it to move over 1/2" or so, retightened and noise is gone.
