    You can hear a howling noise if you listen close in the video all of them spin like normal except the one you can see barely moving in the video. Pulled the axle on that side and it’s not broken!? Also no metal in either rear end.
    Any ideas?

    Drain the gear oil and see if there’s any chunks of metal. And stick in a spring magnet towards inside bottom to see if any metal comes out also.

    Power takes the path of least resistance. If the brake on the wheel that is hardly moving is dragging a bit, its easier to spin the wheel on the other side (which will spin twice as fast). Normal differential action and not neccessarily cause for any concern.

    I didn't watch with volume so I cannot say anything about the howling.
     
    Rideandrepair and Bean Jr. Thank this.

    Do the easy stuff first, drain both, examine what comes out. Refill both with synthetic 75w-90. See if problem improves, worsens, or no change.
