Upper control arm replacement
IMHO
The beat the **** out of it method is a bad idea.
I have seen people beat the spindle at the ball joint toll it is deformed.
Not the way to do it
Pickle forks are just plain bad news.
The tool abblies pressure up on the ball joint stud and then a fairly light shock on the side of the spindle will normally cause it to pop off.
The FSM has a tool that pressed between the lower and upper ball joint nuts. The to above works in a similar fashion but only puts pressure on the ball joint stud in question.
One thing that might help is raising the lower control arm up so the upper is more level.
Giver.s you more room to work
