Things You'll Need:
- Socket set
- Floor jack
- Jack stand
-
Step 1
Lift the truck by placing the floor jack on the frame rail directly behind a front wheel and pumping the jack's lever until the wheel is in the air.
-
Step 2
Place a jack stand onto the frame rail, close to the floor jack. This is to support the vehicle if the floor jack should fail.
-
Step 3
Locate the torsion bar adjustment bolt, underneath the frame rail directly behind the torsion bar. It is embedded into the torsion bar mount, which has the appearance of a two-plated bracket. Viewing the mount from the underside, it is nestled into the mount and accessible vertically.
-
Step 4
Mark the torsion bar adjustment bolt with a grease pen by placing a line on the head of the bolt, and a similar line on the mount brace. This is to give a reference for the bolt's original position.
-
Step 5
Turn the bolt with a socket (18mm for most trucks) clockwise to raise the pressure on the torsion bar. Each full turn will raise the truck about a quarter inch when it is lowered from the jack and stand. Turning the bolt counterclockwise will lower the truck.
-
Step 6
Lower the truck by removing the jack stand and turning the pressure screw on the jack in a counterclockwise direction slowly.
-
Step 7
Repeat the process on the opposite side torsion bar adjustment bolt, as they must be turned equally to maintain stability and be level.
