Front-end noise, where to start?

Got my truck a few week ago. Even when i test drove it i heard this noise and used it to better the price. It is a consistant pulsating rumble/rustling sound. Maybe right or left i do not know. Best heard when ur off the throttle and just rolling. The faster i'm driving the faster the noise and when i slow down the sound slows down. I dont know where to start to diagnose this. My first instinct was maybe a bearing but i don't really know. Suggestions please

Ok i made a short clip with my phone that can somewhat pickup the noise. I have determined that the front wheels make a rapid clicking sound while spinning and the rumbling/rustling sound is actually from the rear. i verified this by jacking up the rear and giving throttle to about 30km/h and letting off to hear the noise. The clicking from the front wheels can only be heard with the windows open or when ijack the front and spin them. Is that normal? What could the rumbling/rustling be from the rear?

you may have a rock stuck in the rear pads or something like that.

i forgot to mention the owner brought it to the ford dealer prior to selling and there were a few things done but surprisingly nothing about this noise. brakes were serviced and cleaned due to some rust. only thing that held the truck back from its safety certification was the tires. They are old and getting cracked and show some uneven wear. but they were rebalanced (maybe they heard the noise and thought it was a possible solution). Maybe its the uneven wear on the tires?

Is 4WD completely disengaged? Jack one side of the front axle up and try to turn the wheel.

Forgot to mention that they also did an alignment

And im assuming it is fully disengaged because i fry the rear tires in the rain all the time. and when i put it in 4x4 it doesn't spin. soimassuming its working properly. i did just notice i cannot turn my hubs

The reason I asked about 4wd is that if its disengaged, all the front drivetrain shouldn't be rotating other than the spindles. It's possible the wheel hubs might be going out. They are a known weak point on these trucks.

Do the tires have an aggressive mud tread?

The tires are firestones and they aren't aggressive at all. Just unevenly worn I believe. I have a deal for 350 for wrangler silent armours used for under a year. I might pick those up and see if it can fix it or rule out the tires being the problem.
