Drive axel touches frame? Help!!

Paid the money for the rig dig report. The only thing it told me was previous driver was an ### hole. 3 speeding tickets and a following too close ticket...he was doing 88mph in ohio

 

It's weird how they tie it together but these are the details on the 4 total inspections. They were all driver inspections which the driver got inspected for speeding each time so he got double stuffed lol

I went thru every air connection today every fitting every bag...I found 2 air leaks. 1 being on a air tank valve that's now fixed, the other being on a fitting under the cab bag.

Also found the bad/loose/bunked up 4x4 lock fitting

Frame looks solid, no bag leaks, I noticed there is a drive train adjustment bracket ... that is sitting under the cab looking back (see images)

 

Alright- after looking over everything, checking every hose and spending the majority of yesterday under the truck...

My conclusion is that the rear springs are warn... it's the only thing that makes sense at this point.

simple fix is swapping cross members but that will not help if a spring snaps

 

I drained all water in the air tanks, changed leveling valve, the valve tou mentioned before has obly a few thousand miles on it.

What did I miss ?
