New Years present to myself was a 2.5 in Autospring level kit with an add a leaf for the rear. Ran into a couple problems, and have three bits of advice for anyone doing this sort of thing on their own.
1) SPRAY ALL NUTS/BOLTS WITH LIQUID WRENCH OR PB BLASTER THE NIGHT BEFORE. Especially if you're working on an older truck
2) Don't be afraid to beat on that steering knuckle to get the ball joint bolt loose. I was able to get the ball joint loose with 2 strikes of a kobalt hammer on the spindle right here
3) If you have an angle grinder, dont even fuss with trying to unbolt leaf spring center pins with vise grips. Go out to hardware store, pick up 2 or 3 metal blades for a few bucks, cut those suckers right off. AAL kit should come with new center bolt hardware.
Here are the before and after pics- Front was raised exactly 2.5", AAL gave the rear ~2" of lift
