Okay, now that I see your track bar relocation bracket, are you really telling me that you checked every single one of those bolts securing it to the factory axle bracket for proper torque? Because, any bracket like this that isn't welded on really needs to have this done. I personally have seen multiple brackets like this tear off because of a lack of proper maintenance. You can have the track bar bolt on nice and tight but any of these other bolts are loose, they will cause enough movement to allow DW to occur. With each episode of DW, the problem only gets worse.
