Front end noise?

I'm having this growling sound that is almost timed with tire rotation and can feel it in the floorboards. Thought maybe a rotor or caliper but have replaced them and still have th noise. Once I break 45 it goes away or is so constant I can't tell its there. But for 10 to 30 its noticeable and speeds up frequency and slows down in direct correlation with wheel speed. Can't hear any difference when up on jacks though. Thinking wheel bearing but looking for input.

 

I'm thinking wheel bearings. Jack up the front wheel off the ground, hands at 12 and 6, and see if there's any play. Don't let it get any worse!

 

Sounds like your wheel bearings to me. It might be your tires, you could try rotating them to see if it changes. But I'm willing to bet good money on wheel bearings.
I got new ones from @05Taco4x4 check out his thread:

I’d vote for alignment issues or the wheel bearings. I added the bearings noted above 6 weeks ago and night and day difference. On mine I could jack the wheel up and spin it and hear the noise, and I had play when tugging from 12 and 6, but from many posts most may not be that bad.

 

Thanks for the input. Ordering new wheel bearings today also found lca bushings are shot so plans in the works.

 

New wheel bearings and new LCA's and no more noise. Couldn't tell you where it was coming from but while the front end was apart might as well do them both.

 

It was the wheel bearings. They are a common failure point in 2nd gens. The needle bearing is also a common offender (growl goes away if you turn on 4wd is the easy diagnosis tool)
