Ball joints 09 legacy

I'm trying to replace the ball joints on my 2009 legacy and I can't get the ball joint to release from steering knuckle. Wondering if there's any easy way to do it or is heating it up gonna be my best option?

 

i used a little pry bar in the slit, and wailed on the LCA with a deadblow hammer until it came out.. always worked for me.

if that doesn't work, snap on now makes tools specifically for the job:

Did u mean the slit on the knuckle or on the ball joint dustboot

 

pretty sure he meant the knuckle. Another trick is to insert a piece of steel in the slit, and thread the bolt in the threaded side of the knuckle to push on the piece you inserted, and press the knuckle open. A big fender washer would probably do the trick.

 

That snap on tool is awesome!! Use it all the time when doing control arm recalls
