i dont think you need the acx but i would use a oil that has the the correct rating in the owner manual. as far as tie rods they have come out with a new one that looks to fix the ends and from bending them at the treads. remember if its to tough you will just bend something else. belt no sure but have had good luck so far with my knock on wood.
