The stock track bar does not cause DW. It is usually the frame side mounting on the stock set up. That is where you need to focus. Make sure you keep it torqued properly at all times. Before you even get DW I would order the hardware kit from Poly and replace all the stock hardware with their kit. Here is the link to it below:
