They all seem to work on some things, but not others. Another may work. Sometimes nothing works except the old smoke wrench.
Added heat can do wonders. I tried just about everything I could think of to get the lower bearing race out of a 30-40 year old Kubota steering box. Nothing worked, and it didn't help that there was only enough room to get the head of a 16 or 20 penny nail under it to pry with. Nails are not hard enough to use as a pry bar btw. Customized junk screwdriver to the rescue.
The solution was to heat it until the ATF mixture I was using (may have been Ed's Red) was boiling, then it ever so reluctantly came out.
Another time I used gear oil and a propane torch to get it thin enough to get the mounting bolts out of a steering box on a Jeep.
Come to think of it, I really don't like working on steering boxes.
