Thanks. This is a tough one cus at ~$70 there is basically no reason to pass it up but I know it will take me all day to swap em out. And when your truck still operates perfectly fine, that's a tough sell...For bushings, if you're in dusty/water-y conditions alot, it could be weekly.
To kill the squeak, NOLATHANE bushings. They're a urethane bushing, but are much more flexible. Also they have a checking on the inner bore to hold grease better.
For a full leaf refresh you want to get the Spring Eye bushing and Leaf Spring bushing kit
