    Good info, @jlglr4!
    I'm mostly familiar with the 2010-13, 5.0L V8 LR4s, not so much 2014 onward, so I'd take your word for it over my guessing.

    I've heard transfer cases sound like that on other (non-Rover) trucks, so that's my only reference, but I hope it's something simpler/cheaper like what you shared, that's for sure.

    Thanks for providing the TSB. I had a look at it, seems pretty straightforward.

    Another member shared with me the shop manuals and diagrams for the LR4 so I feel prepared to tackle anything that might go wrong.

    This is an excellent forum so far.

    I’d agree this sounds like a heat shield. Let us know what you find out!

    Thanks to the advice in this thread, I was able to confirm that this noise is from the heat shield bracket. I did this by climbing a long hill, maintaining 1100 rpm. Right at 1100 rpm the noise started, and as long as I stayed between 11 and 1200 rpm, the noise was constant.

    I looked under the vehicle and the passenger side front bracket mounting point was cracked. I'm going to do add some thin foam pads as suggested in the TSB and that should take care of it.

    Thank you all!

    Have no idea what it could be but to me it sounded like either something electronic activating or a very high speed vibration.

    If you look through the rest of the thread, you'll see the problem was diagnosed and a repair is pending.

    The TSB calls for the replacement of the heat shield bracket and adding the foam--i tried just foam as well and it does not fix the problem. EBay has the bracket pretty cheap.

    Aw, bummer. I was hoping to be semi-lazy and refuse the bracket.

    Oh well, thank you for saving me some time.
