My condolences. I made The Tool last autumn, and mine did come out with some effort. A few points:
Do not try to press out the center piece. All pressure must be directed at the outer shell/housing.
My bushings came out towards the diff. I believe that is standard.
The holes in the axle brackets curves inwards, and an amount of rust will be present in the crack between bushing and bracket. This was how mine looked:



I scraped away as much dirt and rust I could, and sprayed a penetrating oil into the crack. And waited.

Perhaps it will help heating the thing and letting it cool down, to get some movement between bracket and bushing. Just watch out for brake and fuel lines etc. If everything else fails, you can burn out the rubber, cut the shell with a hacksaw, and pound on it until it collapses. You will still have use for the tool when installing the new ones.

Good luck-
Erling.
