The tortion bars run from the lower control arm back to crossmember half way back the vehicle. Turn the bolts counter-clock wise to unload and clock wise to load.Just don't remove the bolt all the way. But like I said, ,I just use a long bar and pry the lower control arm down.

Wheel Drive Shaft Replacement Removal Procedure
Notice: Be careful that the safety stand does not damage or bend any components it may contact.
Important: Lower the safety stand from the lower control arm in order to relieve the pressure of the torsion bar and in order to allow for clearance.
Caution: To prevent personal injury and/or component damage, do not allow the weight of the vehicle to load the front wheels, or attempt to operate the vehicle, when the wheel drive shaft(s) or wheel drive shaft nut(s) are removed. To do so may cause the inner bearing race to separate, resulting in damage to brake and suspension components and loss of vehicle control.
Important: Do not lubricate or damage the differential carrier axle seals during installation.
Important: It will be necessary to slightly start the knuckle onto the drive axle while simultaneously guiding the lower ball stud to its proper location on the steering knuckle.
