Jingling leaf springs

Ok, Im about to lose my mind...... Long story but ill shorten it up best I can.

Ive checked numerous things over the last while, thinking it had to be the springs. Today I removed:
The hitch, fuel tank shield, spare tire shield, removed both ladder bars and re-greased and cleaned joints and torqued u-bolts to 250 ft/lbs........
Still get the godda** ****ing jingle

I Put new pmf lift on few months ago, while installing traction blocks/bars I had my leaf springs spread apart on me and the alignment pin actually fell through and into the 7"block body
So I wrangled up some rebar and it was a perfect fit so I used that as my center pins.
When going over sharp bumps only the rear end, seems to be on the rebound I get a jingle like Ive got tire chains hanging from rear bumper.


So, my findings today sums up my initial thought of leaf springs being the culprit but I dont understand why......

Any ideas short of finding a new/used set of spring to put in?

You can get new center bolts. You just gotta find a spring shop and give them some dimensions. I'd feel better redoing it than waiting for it to give you issues. There's a good chance that's what's causing your noise as well.

You say you used pieces of rebar for center bolts in the leaf packs? so the spring packs had nothing holding them together except the pressure put on them by your u-bolts holding them to the blocks? i'd say that's your problem if that's the case.
