You are correct, it is doable!!

But for a DIY'er with no garage, scrap metal laying around, and no power tools, this makes a world of difference. The regular clamp style ball joint press is huge compared to this, and it tends to rotate once it is very tight using hand tools. Since i had the control arm in the car, it was very hard to work with it as it wanted to rotate all the time pressing against the floor jack supporting the control arm ...it was nasty!!

this specific tool is wonderful...super easy ....

thanks

glad it was easy with the tool-

Looks massive compared to the AZ tool I used. It doesn't take huge effort with tightening the bolt either- it's not a super tight press fit (could be rusty). I just used an adjustable wrench and held it in one hand with tool. Then it is pretty tight-just give it a nudge with a 1-2 lb hammer. It will drop out quickly.

FYI when I did it.. the dealership was the cheapest on the parts too.
