I don't have pictures of this process unfortunately, but it's a dam nastee job!
There are different forms of spring and shackle bushings used on all ihc leaf-spring rides, depends upon what actual vehicle platform you are working with. Some use a "bonded" bushing where the inner and outer sleeves are vulcanized to the rubber isolator. Others use a "sliding" inner sleeve inserted into the isolator,..some have a two piece rubber (or urethane) insert, some are one piece...some have no outer steel sleeve. On some versions the non-moving spring eye uses a totally different type bushing set compared to the moving end.
But currently I do one of two procedures (and sometimes a mixture of both). And that definitely involves a reciprocating saw, many times a gas axe, and a c-clamp-type ball joint press. Each one is different, sometimes they literally fall out with a few whacks with a drift and hammer! Also depends if the bushing system is the one mounted in the spring eye, the actual shackle itself, or the frame-mounted spring hanger.
If accessible, I always just use the saw with a milwaukee "torch" blade that has had it's back ground down carefully to allow the blade to pass through the inner sleeve before beginning the cut. Then slice straight through the inner sleeve, what's left of the rubber (that will melt and make a big dam mess so don't do it in the living room!), and then through the outer sleeve (if present). If ya scratch up the spring eye it doesn't matter, just polish it out before installing the replacement bushing set.
Sometimes, I "burn" out the inner sleeve and rubber remnants with the torch, then use the saw to slice through the outer. Again...big freakin' mess that makes much smoke and dribblin' fire so be careful!
I used to take the "gentle" approach, but that just leads to increased levels of tooling and bigger hammers. By slicing horizontally through the entire bushing system from the beginning, then whether you use the hammer/drift, or the ball joint press with whatever kinda "adapter" ya can rig up, you don't waste time and muscle escalating the procedure!
On occasion, I go to a lotta trouble to tool up for the battle, then when I make an initial cut the whole dam bushing just jumps out! So always see if ya can whack it out with a hammer/drift first, sometimes the planets line up in yore favor!
This issue is not peculiar to just ihc-produced stuff with a leaf spring suspension, it pertains to all leaf-sprung vehicles.
