So this past weekend I wanted to put rear shackles on my blazer and I thought it would be an easy install. which is should have. only problem is if you have an older blazer you have the problem of rust. It took me 12 hours to remove the shackles and bushings from the right leaf spring and the frame. I took some pictures and I'll have some instructions on how to make it smooth.
1. Jack it up and put it jack stands on the frame. once this is done put the jack under the pumpkin and just jack it up a little.
2. The two bolts you will have to remove are going to be very tight from rust if you have an older blazer. I used an impact wrench on one side it worked pretty good. A long socket wrench would work as well. you may have to pound on the screws to get them to come out.
3. Then once you have the screws out the shackle will come right off. The easiest way to put the new shackles on is to take both shackles off at the same time or else u will have to pull down on the leaf spring.
its as easy as that if you don't have any rust, my problem was I did have rust. What I did was take a torch to the bushings and melt the rubber inside and eventually push the rubber out. after that there is still the metal casing around the bushing still in the hole at this point we used a saw-zaw and cut down and bent and twisted the casing untill they popped out. it sounds easy but it takes a long time to do this.
Here is some pictures:
heating the bushing on the frame
the new bushing on the leaf spring (should fit really snug in there)
the side that didn't give me trouble
the bushing in the frame it was really rusted in there
almost have it out at this point
the mess we made
any questions I'll be happy to answer them
