From the pic you can see how I mounted the puller. I tightened it, hit it with a small sledge, tightened a bit more, another hit and the control arm popped off.

Only one screw removal needed to pull back enough plastic to get to the bolt on the other end of the control arm. The plastic covering has a cavity for the bolt to back into before lining up correctly. Two 18mm wrenches needed for each end of the bolt and an 8mm for the screw that holds the plastic. When you're putting the bolt back don't tighten until you secure the ball joint nut. The rubber bushing doesn't spin when the bolt is tight (duh). Tighten the nut as tight as you can and then tighten some more from the head of the bolt while keeping the nut secure.

You'll need a T40 torx to hold the ball joint while you tighten the nut with a crescent wrench. As soon as you get it snug you can continue with a 24mm socket. That's about it. I still have to take it to NTB for an alignment now that everything's solid up front.

Spent 5 days trying to figure out how to safely remove my control arm from the wheel hub. Tried everything I could think of; tie rod pullers, 2 jaw pullers, brute force hammer ... until BinaryAgent showed a photo of the correct tool he used ... Controlarm was out in less than 60 seconds.
