Hello I came here for some advice. I need to replace tie rod ends, steering dampener, pitman arm and ball joints on my 05 5.7 4WD SLT Quad. I am aware of the upgraded mopar steering system. I am curious if the 2009 tie rod ends are an exact drop in replacement as an upgrade, or is the mopar upgrade kit different? What I mean by this is can I go on rock auto and just select each individual part from an 09 and build the upgrade myself (sleeves, pitman arm, pitman ball joint, left tie rod, right tie rod), and save $150 vs the $350+ on the upgrade? Thanks.
