There isnt alot of room on the knuckle for the puller, so make sure its a 3 arm puller. A 2 arm like the one I used was very unstable, but it worked. I ended up hammering the adapters in a little at a time using a block of wood between the hammer and adapter.
Everything else is pretty straight forward. You will have to remove the ABS wiring from the fender well on the drivers side (IIRC) to get the upper arm bolt out. Just a few misc bolts but one, the one under the battery, was the hardest to get to.
Also, not sure what kind of lift you are running, but on mine with 881 springs, having the caster adjustment set at 0, and camber set right in the middle, the caster was about dead nuts in the center of the adjustment range and camber was darn close. The caster setting of 0 on the arm gives you a +2 degrees of caster.
