Yeah, I tried an impact and the ball joint just laughed at me! I was kinda worried I was gonna wreck the socket too. Heat worked well this time. I'll I definitely try the impact again next time.
You need a REAL strong 1/2 inch impact to remove most upper ball joints in a car that had them in there for decades.
BUT.
If you worked at a heavy duty truck repair shop that uses 3/4 inch air guns, ball joints come out easy peasy.
Those impacts have a lot of kick to them.
