There's really nothing to it. The way I did it was this:
-Disconnect sway bar link.
-Jack up the suspension to take off the the tire.
-Put a jack stand under the FRAME and take out the jack from the suspension so it will flex to the ground.
-Disconnect shock on the bottom.
-Disconnect the spring from the I-Beams. DO NOT FORGET that there is an access hole on top of the spring's housing thing.
-Remove spring from assembly. At this point there should be nothing holding the I-beams up. They should be touching the ground.
-Now you need all of the space you can get for these suckers to get on there. Jack up the frame as high as the jack will let you and keep a jack stand under that b****!!! You will be pushing those TTB's as far down as those suckers will go to get the spring and spacer on there. I forgot exactly what I did to get it in there, you just have to be innovative and put in a little elbow grease.
-Now that the spring is loosely in there, jack up the beam little by little to get that spring set in place.
-Once it's set in place, bolt that spring in there with the included stud extenders.
-Attach the shock.
-Lift the beam up to the height the sway bar link is at and attach it. Trust me, trying to force that bolt in for the sway bar is something you don't want to go through...
-Put the tire on and move on to the next side.
They you go, that's about as good as I can get it. PM me if you have any questions if you do decide to go through with this later on down the trail...
