Does anyone have tips or advice on changing my Leaf springs? I have never done it before, but I don't think it will be that hard, but who knows.

jack up the back of the truck, jack stands on both sides of the truck. use a scissor jack or better would be a race jack/floor jack, put it under the center of the diff, and lift slightly to take some of the weight off....then, remove bottom shackle bolts, and put more jackstand under the axle to support it...then unbolt the u-bolts and the perches, then remove the front spring hanger bolts....reverse the order to reinstall, and make sure you use new ubolts

different truck, same general concept. Do one side at a time so the diff does not do what is pictured.
