Help! Question about lower ball joint

Anyone know how to get this piece off? It's not coming off no matter what I do

 

It’s a lot easier when it’s still attached to the truck.
BIG hammer and a smack to control arm/ball joint mount.

At this point, you need a ball joint/ Pittman arm tool.
The 2 jaw style worked best for me on the Tacoma.

 

Puller, lots of heat or reattach and hammer it off in the truck.

 

I got it. I just smacked it lol. Thanks for the responses. On a different subject how to y'all get the tie rod disconnected? I gotta add the extension but after taking the cotter pin off and the nut it still doesn't want to go

 

Same thing, hit what the tie rod goes through with a heavy hammer, so the knuckle and count the amount of turns to remove it. Make sure your alignment is scheduled for the day after you're done your job
