Once you have loosened the retaining clamp, drive the end of a flat chisel into the "split" at the end of the Pittman arm. That will spread the threads enough to turn the C/V off the arm.
BUT, you need to carefully COUNT the actual number of turns the C/V rotates for it to come off. Count to the nearest 1/8th turn and record it. When you rebuild your C/V, you can then re-thread it back into the Pittman arm to the exact setting it had prior to removal. Not doing so is a PITA situation.

I would screw it in until it bottoms out. It cant be more than a turn or 2. Its easier to count that way

Try a bearing puller. Its split in the middle so you can come in from the sides.

I used a pitman arm puller from Advanced Auto - https://shop.advanceautoparts.com/p/...044%7CL3*16235
Before putting it on an drenched the joint in penetrating oil for a couple days. When I put the puller on a torqued it down quite a bit, then walked away. Did a little work elsewhere, torqued it some more, then walked away. Repeated that a few times and then bang, off it came.
