Mark the nut so you can be sure of the turns. You can count the mark as it goes around.
8 turns = 2"
Measure each side before, during and after the lift cranks. It may be 8 on one side and only 7 on the other.
I know you're lifting, but for all the others reading that may be lowering? ALWAYS use the final adjustment going UP. Thus a 2" drop is 9 rotations down and 1 back up.
