I replaced mine on my 04 with the old Y system. Even had a new adjustable track bar, steering box and high performance steering stabilizer installed but DW still remained. So I went to the upgraded T system from synergy which is the 09 T system. DW gone! Napa and both Mopar offer this upgrade. Synergy also recommends going to the 09 stabilizer and pitman arm which i also did. with the 09 stabilizer.
