    I need to replace all 4 leaf spring bushings, that go in the spring hangers. It’s an air leaf suspension and was wondering if there was a particular procedure to do this the easiest way? Any places other than Pete that offer good quality?

    Start soaking those bolts in PB now, and make sure your dealer has the frogs available JIC.

    I'm pretty sure on my feet, so this ain't for everybody. I have a long bolt the same size as the bolt through the bushing. I stack the right size washer, stand on the frame, and drive them out with a sledge.

    The more wore out they are, the easier it will be

    Make sure you get the correct bushings, they all look pretty close, low air leaf, Air track, and air leaf.

    On my low air I torch the bolt head off and set the rubber on fire and let it burn. Knock the bolt out and what'd left of the bushing. Clean it out and install new. Pretty easy job. 30-60 min per side
