just did mine yesterday. also changed the radius arm bushings.
Just pull the bolt out of the axle pivot, remove the nut from the radius arm, hang the brake calper out of the way and unbolt the shock and sway bar. you will need a heavy duty tie down strap or two, or a come along to pull the axle forward and every thing should drop out with a little prying. I wouldn't call it easy, but just never panick, it will come apart and it will go back together. the instructions say to do one side at a time, but honestly if you do both I think it would go better. Let the axle pivot bolts on both sides till last that way you can swing the entire assembly both ways to get the radius arms back in place.
The hardest part of the whole job for me was getting the axle pivot bolts loose. Didn't have the right metric wrench for the nut so I had to use a 13/16 open end. then I used a jack for leverage to bust it loose. soak everything for days with penitrating oil so that the bolt comes out of the bushing. Then I burned the old rubber ones out with a mapp gass plumbing torch.
Very much worth doing, tightens the entire front end back up.
This is probably more info than you needed, still fresh in my mind if you have any questions
