I replaced the front spring, removed and disassembled the rear spring, and alternated leaves when re-assembling, and it still leaned.

What worked well was to jack up the truck on the low side with a floor jack and a wood block against the frame at about the center cross member location, then loosening all the spring u-bolts front and rear, then jacking it again as high as you dare, and then tightened all the u-bolt nuts while the frame was still on the jack.

Was nearly level for quite a while but has started to sag again.
