It's pretty simple, but you do have to get under your truck. I did it in my garage with a cheap jack and 4 jack stands. The torsion bar crossmember is just behind your transmission. You will see 2 bolt heads(7/8" I think) on the ends of the bolts that go thru the torsion bar adjusting arms which are on the ends of each torsion bar. You simply turn them. One way to raise the truck, and the other to lower it. Make equal turns for each bolt and take measurements from the ground to bottom of the front fenders on each side to make equal. You need to be on a level surface, of course. You may have to raise it and lower it a few times. It will also help if you kroil the threads on the bolts. I had to use a 1/2" socket wrench with a breaker to get them started. Once you change the height, the truck should be re-aligned anyway according to my shop manual. I hope this helps.
On a side note, I removed the bolts and special washers completely. I them cleaned and oiled them for ease of adjustment in the future.
