I cranked my passenger side 5 turns and my drivers side 4 turns, which leveled the two sides and raised them. The back was at 38.5 to the fender directly over the center of the tire, the front was 35.75 at driver side, 35.375 at passenger side. Now they are at 36.875.
I am going to order the ford keys soon. I want the truck within .5" of level. Instructions for install are at:
