I don't particularly like harbor Freight at all, but they have a few different ones ...and inexpensive
as noted above. And like you say, there's lots of stuff online.tuning-fork style tool would work good
Most times, I've had success with a 40 oz ball pein hammer. Failing that, I also have a 6 lb sledge with the handle cut down for one handed operation.so,......I've got a 1963 Ford 4000, Industrial, the power steering cylinder is leaking, I figured how TUFF could it be ?, remove two bolts and remove cylinder.........so I google it and some guy say's "just hit it...hard.....with a BIG hammer.........I used a splitting maul an a piece of pipe , ball joint #1 broke, ball joint #2 is still intact....for now,.....anybody else run across this ? I went down to autozone , ask the kid behind the counter if they had a "ball joint removal tool" ?........he looked at me like I had a 3rd eyeball in my forehead & asked " what's THAT? "...........I turned around an walked back out to the truck an left.
Yes that is how I take all of them off the other hammer against back side it helps to add shock and cause the metal to temporarily distort making it let go of the stud.This last post reminds me of a technique my dad used sometimes to get them apart. You don't hit down on the stud to get it out, you put a hammer on one side of the part where the stub goes through (just hold it there), and then hit the other side of that same part with another hammer. The shock would break it free (may take more than one blow).
