I have a 2005 4WD Chevy Tahoe. I recently noticed a clicking sound coming from front end that turns into road roar once I get above 15 miles per hour. It does not make this noise all the time. I stopped by my mechanic's shop one day when it was making the noise and he believed it to be a wheel bearing. Upon inspection he found nothing happening with the tires, bearings, etc. Turns out that my front differential is the culprit. He drained the fluid and founds lots of metal. I only have 65,000 on this vehicle and it has been maintained to the max. Any ideas?
Yes, Rebuild the differential BEFORE it leaves you on the side of the road!!!!!
SOURCE: noise in front end, sounds
You say the rear wheel axles and bearings have been replaced, you mention nothing of the front wheels, you have the symptoms of a front wheel bearing being worn out, remove them and check for pitting in the bearing rollers or the bearing races, I am sure you will find a problem. Hope this helps solve your issue with the bearing noise.

That's indicative of a wheel bearing, which is why you were told to change that out. However, it's also possible that the carrier bearings in the differential (where the drive axles attach) have gone bad. That happened to me on my 300ZX several years ago, and I had to replace the diff bearings. I would have them checked out somewhere other than a dealer (you'll probably get a better price from an independent shop).
As a sidenote, to be sure it wasn't a wheel bearing, if you hear it quiet down in a turn one way but get louder in a turn the opposite way, it's likely the wheel bearing. If you turn left at speed and it gets louder, then it's the right bearing (since you're loading up that side of the car). If it gets quieter in a right turn, it's the right side (you're unloading that side of the car and not putting as much weight on it, so it doesn't drag as badly). See if you get that symptom just to be sure that the wrong side front wheel bearing wasn't changed.
SOURCE: Vibration and noise from front end while driving
Jack up the front end and put stands under it and block rear wheels. Look at axle boots and see if they are cracked. Try turning wheel back and forth sharply and see if you can hear any clicking. Problem could be outer axle joints. If the boots are cracked or you hear a clicking noise you will have to replace the axle. The axle and boot come as a complete unit. Please let me know what you find out.

the tires make steady noise , check the wheel bearing as noises get high and low at the same speed , and i also would check for diff if it's 4wd.

The noise you're hearing is consistent with a bad wheel bearing. It's true, the only way to actually tell is to pull the hub/bearing. I'd try to isolate what side of the car the noise is coming from and pull that wheel. If it's not a wheel bearing, it could be transmission related but these things are usually solved by replacing the wheel bearing.
