As I needed to replace the shackle bushings on my wagon, I read this thread with interest.
I took Mart's approach and hammered out the bolts. I then started to cut the jacket with a hacksaw. This seemed like a tediuos process, so I tried to think of a better way to remove the jackets.
I decided I was going to use the all-thread I had used to remove the springs.
I placed a deep 11mm socket at one end and a section of pipe, the same diameter as the spring perch, at the other end.
I then ran the all-thread thru these with a washer and nut at each end.
I simply turned the nut and pushed/pulled the jacket out.
I know one side was in pretty good, but the other side and worn thru the jacket, so that came out pretty easy.
One, note, I did work the bolt back and forth with a pipe wrench and pipe before I hammered it out.
Thanks for all the ideas.
Keep V-8ing and 4-banging!
