by putting my 04D2 on jack stands and running the truck to find the additional ticking i only hear when in gear and accelerating?
am i asking for death

You might be better off spending the $100 or so to have a shop run it on the lift to diagnose it for you, and then you can do the repair.
One of my buddies did it, but it was with a 2WD truck:
Lifted up the back, lowered it on railroad ties. Ran the shit out of it while underneath with me shifting gears in the cab (he was looking to see if he could tell the driveshaft was out of whack). I guess you could do that with a Discovery...essentially building a "lift" of sorts so even if it vibrated forward or back its staying on the ties, but seems like a lot of work to do that front and rear since it's AWD.
I second the going to a local shop and asking if you can just put it on a lift and run it for a bit.

If it only makes the noise when accelerating, try putting load on the engine by giving it gas while holding the brakes.
Likely an exhaust leak at the manifold.

Thanks for the replies. I have in the past put the truck up on jack stands and run it but i wasn't under it or in the engine compartment.
I've spent more time than I would like to have researching and the three things I'm going to check without the engine running (but still up on stands) are 1-heat shields 2-cat and 3-exhaust manifold to downpipe gasket
I already have an exhaust leak in cylinder 8, and a noisy top end.
I just can't wrap my head around why if the car is rolling, and is in N, and i depress the accelerator I don't get the sound.
And if I do decide to kill myself, i"ll livestream it.

Have the same thing - only in drive and only when cold...after it warms up it goes away. Is yours there all the time? I rev in neutral also and it does not make the noise. I understand the load issue but exhaust is exhaust - air is air under load or not??
I am going to replace the downpipe gaskets, and manifold gaskets.
If there's a load on the engine, it will torque on its mounts. This can exacerbate an exhaust leak, since the downpipes are held to the body further back. A small or non-existent gap can open up.
Im not following. you say no load, but if I'm depressing the gas pedal, isn't that putting load on the engine.?
