*use pipe wrench to twist the ball joint base within the knuckle by grabbing it from the bottom
*use an air chisel to impact rattle lose
*find right sized puller that can grab ball joint's nut shaft and pull downward
*remove the steering knuckle and then attack
*careful not to damage the ABS sensor, bearing etc, so no torch heating

Perhaps others here will have some other suggestions or tricks

I also found that a lot of posters here talk about all of the front end suspension parts being really easy to change but when you probe for details often they re-use the ball joints. I would agree that other parts on the front end were reasonable to change but the ball joints coming out of the knuckles were chore.

I will admit that it is the one thing in years that I took my car to a local small indy shop for. In the end he used an air rattler (like an air chisel with a u shape attachment) with 3 minutes of impacting to rattle them loose while pulling them downward. Took him 30mins per each ball joint to remove. The longer I watched the better I felt about paying a bit.

Hoping yours might come easier than mine (90K miles). I will say that changing out the ball joints was worth it. I had roughly a week with all new bushings and the old ball joints. Once I had the new ball joints in there the X tracks like a car again and the rattle which I could hear over speed bumps which dealer and previous owner never could find are fully fixed now.
Thanks, Junky! I appreciate the feedback; these are good tips.

I've done the lower control arms and the tie rods and, as you say, they weren't that bad. I was hoping these ball joints wouldn't be bad either, but I can see now that it won't be easy. I've done these before on other vehicles where I had to take the knuckle off and then drive the ball joints out with a big punch and sledge hammer. Those were pressed in ball joints, so I was hoping these ones would not be quite as bad. But, with all the crud and rust in there, I guess I am probably having to go the same route here. If anyone else has any good ideas, feel free to chime in. I will let you all know what eventually ends up working out.
