ok then
so its the drivers side torsion bar you need to tweak
underneath the truck about half way allong you will see the end of the bar with the adjuster
loosen the top nut , then wind down the bottom nut . you will need around 4 full turns, a marker pen will help you count.
do that tighten top nut back up , as this locks it then measure again and take for a short drive.
repeat above to get it exact
ideally you want 1/2 inch lower at the front but equal side to side
but once you have done it once , its easy to work out and tweak exactly
