ive tried the search button but i cant find a thread that walks you through the process.
does anyone have pictures of how to crank the torsion bars, or just describe to me where the part is that i am supposed to tighten

 

I hope this helps. The drawings in the section will not copy/paste but the text does,

10 — Front Suspension Lower Arm Bushing Center Bolt-to-Front Wheel Spindle Dimension (Ride Height)

NOTE: For four wheel air suspension (4WAS) equipped vehicles, the front air shocks need to be vented before measuring or adjusting ride height.
Vent the front air shocks.
Using the scan tool, select AIR SUSPENSION CONTROL MODE under the ACTIVE COMMAND MODES menu. Select VENT FRNT command to deflate the front air shocks down. Hold for 30 seconds to allow complete system venting. Do not disconnect the scan tool. Keep it at the same mode as specified to keep the system at diagnostic mode at time of ride height measurement. If the scan tool is disconnected, the system will go to the operational mode and based on signal inputs, will level the vehicle to specified height (trim or kneel).
Raise and support the vehicle; for additional information, refer to Section 100-02 .
Use a hoist with frictionless plates to support the front wheels.
Normalize the vehicle static ride height.
Measure the front suspension from the center line on the nut side of the front bolt on the front suspension lower arm (3078) to the ground, and record.

Measure the front suspension from the bottom of the front wheel knuckle (3K185) to the ground, and record.

NOTE: The ride height specification for base vehicles with new suspension components is higher than the specification for vehicles using original suspension components to allow for new component settling. For additional information, refer to General Specifications in this section.
To obtain the front suspension ride height, subtract the measurement in Step 3 from the measurement in Step 2.
If the measurement is out of specification, ride height adjustment is required.

NOTE: For the front ride height setting procedure on vehicles equipped with four-wheel air suspension (4WAS) system, for additional information, refer to Section 204-05B .
NOTE: Use only hand tools for this adjustment.
NOTE: The ride height measurement on the opposite side from the adjustment may change.
Adjust the ride height by tightening or loosening the torsion bar adjusting bolt.
Inspect the ride height on both sides after each adjustment.

NOTE: Do not under any circumstances "save rear" ride heights — there are precalibrated values already stored in the control module.
Once the mechanical ride heights are set, using the scan tool, select SAVE CALIBRATION VALUES under ACTIVE COMMAND MODE menu to calibrate the module. Trigger through warning message and save FRONT (turn from OFF to ON).

 

ok this is perfect thank you
but i am not sure where the actual part is that i am supposed to tighten, i only took a quick look under the exp, so maybe if i look harder it will pop out at me but i didnt see anything obvious to tighten down.
sorry i dont have any knowledge of torsion bars, all my vehicles have either been 2wd or old trucks that had solid axles in the front.

 

The torsion bar adjusting bolts are within the red circles in this picture. They're actually underneath and sandwiched between the two walls of that support member.

 

thank you, i think im all set now
