Re: Uniball tapered bolt stuck in spindle
The big C-clamp style multi-functional tool (^^^) is the correct, non-destructive way to go. The illustration above shows the tool configured to press a ball joint INTO a control arm, but by configuring the various cups and adapters you can install and remove ball joints, uniball studs, wheel studs, etc. without resorting to any brute-force methods.
In your case, since you have apparently already severely deformed the end of the uniball stud through application of the "bigger hammer will fix it" approach, you may have to grind the end of the stud flat again so the tool doesn't slip off, and the deformed end of the stud can pass through the eye in the spindle.
These tools can usually be borrowed from the larger, chain auto supply stores after a hefty deposit.
(If you are stuck in the jungle, and have no access to the "right" tools, you can try another approach. The objective is to apply a shock load across the tapered hole in the spindle to break the interference fit of the tapered pin. Have a helper hold a heavy steel object (5 lb maul, 10 lb sledge hammer, etc.) tightly against the OPPOSITE side of the eye of the spindle, and strike a very sharp blow with at least a 5 lb maul on the spindle eye, directly opposing the head of the other tool. This will ensure that the energy of the strike is actually delivered into the eye of the spindle, and not just dissipated into moving the spindle.)
