Is the nut on the power steering pulley clockwise or counterclockwise to loosen it? What size is that nut also? When I put a 14mm on it, it still feels kinda lose...

 

Are you doing the Evosport UD Pulley package? If so, I believe you need a Power Steering Pulley Puller for that matter. I have other pulleys installed by an MB tech and he couldn't pull the PS pulley out because MB dealers don't just replace the pulley itself... hope this helps...
