Follow the torsion bar back. You will come to the adjustment bolts. Jack
up the front of the truck a bit, thereby reducing the weight on the
torsions. Now tighten up the bolts a couple of times. If its not up
enough tighten it a bit more. Take measurements in the biginning. Use
your imagination where to take the measurements from. You shouldnt lift
the truck anymore than 1" to 1.5". Anymore than that and your front end
is going to ware out to quickly.
