Drive axel touches frame? Help!!

This is best solution, take it to a shop specialized in frame . I took my last truck to "frame and alignment" north of Wacco, Texas, I-35, there's a yellow truck lifted for advertising . The owner David worked on my truck, the old man knows all tricks, measured frame, driveline angle, found a frame twist put it on rack and straighten it, for about 2500$ if remember .
There's a good high tech shop called Jossam in Orlando, FL, they have all kind of videos on YouTube specialized in frame alignment problems.

 

do a rigdig report see if its been turned over. you should have done on before you bought the truck tho.

 

Did anyone EVER grease those U joints?" Those shaft ends and joints look like they were rusted dry since Moses put it together before loading with household goods to leave Egypt thousands of years ago.

Im sorry about picking on such a minor detail, but it caught my attention. That poor truck must have arthritis all the time... maybe that's why she squatted down when it's enough is enough back there.

I see signs of more grease that has slowly dried out since 2007. No one cared enough to love on that poor truck to wipe away the old grease and replace it with fresh.

And that frame tells me no one has given it any love at the Blue Beacon or some such. Bet you some of those bolts are loose enough now to spin by hand. Or opposite rusted to frame pernamently.

 

Step 1
buy 4 pressure gauges and put 1 on each airbag.
Cheap and you can do it yourself.(inside or outside the cab ,as you see fit)
Will rule out any fault with the airsupply to the bags.
Step 2
The plate above the axle,fixed to the frame with the 2 bolts,is there rubber or rubber traces on bottom off them?
My geuss is they are stopblocks .
