Noise when truck start rolling at first gear

[snailexpress]

Drive lines angle or synchronizing is out of spec's. Worn out suspension springs, bushings, leaking air bags, ride height valve adjustment, bent frame.
Here is short video how drive lines work and how drive line end can swinging when angle is out.

Noise coming from clutch torsion springs absorbing drive line velocity deviation.
My truck does same noise. I'm on second clutch just because torsion springs slots were worn and some springs broken because it's weakest point in whole drive system.
