Hi, i have a 1990 f-250 4x4,the truck was leaning lower on the left rear side,so i put new leaf springs on both sides,and it still sits the same way.I measured from the bump stumps,on both sides and there is a 1.5" difference.The shackles don't look bent or cracked.I even measured where the top four springs meet the bottom over load spring and there is a 1.5" on the left side again.Anybody have any ideas.Thanks.

You will need to let the experts look at that one in the tech forums. Click on the Forums tab at the upper left and look over the list. You might try the suspension board: https://www.ford-trucks.com/forums/forum64/ or you can try the one for your year of truck. When that problem gets solved stop by your local state chapter and see what's going on in your state: https://www.ford-trucks.com/forums/forum182/
