I am a new member, don't know all rules and regulations, user name is Darel H. Having problem with 2007 Chrysler 300. front end vibe at about 25mph up to 50mph. then it pretty much quits. changed outer tie rod ends and bearings on both sides. also had tires balanced and rotated. Rotors pads and calipers are in good shape. Still has the vib. any suggestions?
