Your first post says its in the bump stops all the time: "It does touch the bumpstops at ride height."
Your suspension is now the bump stop, which is completely wrong. You should be asking why they don't fall out after a block down the road.
Undo the the mods you've done, or get a designed drop. I'd guess the thing is beating itself to death as you go down the road...

While I agree w/this theory, the issue will be how much does a guy spend vs. the quality of the drop they ultimately end up with.
My 74 had (has) a similar issue as brad_man_72. The drop was done w/3" Bell Tech spindles & a coil cut from the original V8 springs. The amount of drop is about 6" in the front. You could not slip your pinky between the tip of the OE bumpstop & the bottom of the factory x-member.
The options to stay off of the bumpstops are to trim them down or use shorter ones, raise the truck, or modify the mounting points of things to retain the same drop amount while increasing the amount of travel (Dropmember, frame-Z, x-member notching).
I tried the shorter bumpstop idea but that only 'moved' the contact point from the bumpstop/x-member to the top of the tire/fenderwell. You can retain control of the truck w/the bumpstop hitting the x-member; not so much w/the tires 'biting' the tops of the fenderwells. Remove the bumpstops alltogether? The lower a-arms would be digging-in/dragging on moderate/agressive dips in the roadway.
With so little gap between the b-stop & x-member on my set-up, it actually road fine on 'maintained' roadways. On roads that were not up to snuff? You definitely slowed your pace & had a pucker-factor. The alternative was to start cutting the frame to raise the suspension mounting points because the drop amount is/was 'spot-on'.
