Removing an upper ball joint

Yea, what they said about the special socket. Long cheater bar and something to hold the control arm, if it isn't still on the car.
I have wedged them in the class 5 hitch on the back of my truck. Hey, it worked. Unless your bench is anchored and you have a unreally big vice to hold it you gotta do something.
Another thing I have done is grinding the top off. Taking the guts out and cutting a grove from inside seems help relieve pressure.
