The purpose of a bump stop is to stop the metal suspension parts from crashing into the frame or each other when the suspension has travelled to its limit.

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...
