This is my first experience with All wheel drive transmition. When you take close turns and accelerate a noise comes from the transmition. It sounds like something is skipping. Did not know if this a normal noise from an all wheel drive or a problem. The all wheel drive button is set to “AUTO”. No problems are noticed when driving straight or taking wide turns.

Hit in the rear axle may have damaged bearings or brake parts. Jack up the side you hear noise from, put on stand, then have helper rotate wheel while you look underneath and listen to see where noise is coming from. Use length of old fuel or heater hose, one end in ear, to locate exactly where noise comes from.
This is a hard problem to describe, I know, and I will toss out a few possibilities. If the noise occurs when the car is accelerating, it can be motor mounts, or carriage mounts on front-wheel drive vehicles. Transmissions can bang into gear. Drive shaft u-joints can bang before they fail. C-V joints in front wheel or 4 wheel drive units can bang when worn out.
The exhaust system can break loose and bang on the frame. Brake calipers can rock in their mounts and transmit sound. Tie-rod ends can make a knocking noise on every bump you hit. There were recalls on gas tank straps for some Ford made units, so a loose gas tank can bang.
Assuming that you have already ruled out the brakes, severely worn engine mounts can transmit vibration and noises from the engine which are not normally heard. You don't say in what I see but is the vehicle two or four wheel drive. Since you mention CV half shafts I have to assume it is at least front wheel drive. If the vehicle is four wheel drive then there is a front differential with bearings in it that may be at fault. Have you done both sides when you say "hub assembly". Defective hub bearings will make grinding noises which will change tone or intensity when turning, accelerating or braking however the noise is usually fairly constant unless they are only just starting to fail. CV joints don't normally "grind" unless they are really bad. They usually make progressively worse "clicking" sounds or "clunking" sounds especially when turning hard, changing gears or direction of travel (forward to reverse and back again). Do you have non-stock tires/wheels? Larger/wider than factory spec tire sizes can rub the fender wells when the car is moving or turning. Another thing it could possibly be is the air dam below the front bumper. If it is loose it will push down in the airstream while the car is moving and rub on the ground.
is it like a growling noise, or a metallic "metal on metal" noise, is it clicking? when do you hear it? Common for wheel bearings to go out on those in my experience. usually you can narrow it to a wheel bearing if when you sway the car, you hear a growling noise towards the heavy end of the car, meaning if you turn to the left, causing the car to naturally sway right, the right hand tire front or rear starts making noise, thats usually a wheel bearing. If its a clicking noise while cornering and especially when corning with acceleration, thats usually a CV axle. if its a metal on metal noise, that can be a brake pad worn to low, or even just a simple backing plate to the brake rotor touching and rubbing the rotor.
Had something like this with my much loved 6 cylinder Camry. Turned out to be a wheel bearing. You can check by raising the rear wheel off the ground with the jack and if you can move the wheel in and out, you need a wheel bearing. And it is a safety issue - when bad enough the wheel can come off the car, definitely a life changing experience. Check both rear wheels, just take a few minutes of your time. Don't believe the Elantra or any other front wheel drive car has a differential, those are used in rear wheel drive vehicles.
Check the idler pulley on the serpentine drive belt,it's mounted on the passenger side timing cover close to the cam gear,and could transfer the noise through and make it sound as if it coming from inside,and it's an easy check and requires no dissambley.I've had personal experience with this in my professional trade,I do industrial maintenance and repair and have seen bad bearings transmit noise down the lenght of a solid 8' shaft.Loosen the tension on the belt and check for play in pulley,spin the pulley and see how it feels,should have a smooth feel.Go to autzone.com and register they have a good online manual for your truck that you can download and print.
