what you need:
- vise
- metal hacksaw
- couple of different size nuts
- hammer
1. punch the inner metal tube out of the rubber. If you can´t punch it out, use the vise and 2 nuts as a press


2. disconnect the blade from the saw to slide it into the bushing and connect it back when it´s in. Make 2 cuts in the rubber so that you can remove the rubber from the outer sleeve

3. make 1 cut into the outer sleeve. be carefull not to cut to deep into the spring eye. When done, remove the saw and give the outer sleeve a few punches to compress it. Now you can punch it out with a correct size nut.
