Has anyone ever remove the belt tensioner pulley assy on a 2008 4.2 liter V8 motor. I took off the two bolts that hold the spring on and the large long center bolt in the center pivot and it still won't come loose. Do I need to also take off the three bolts from the bottom of the housing to get it off or do I just force it off of the center pivot? I need to change it out as my pulley is seized. I'm try to see if I can just change the pulley and not the whole tensioner assy that costs over $250 :-k
