In July 2003, ODI opened PE03-032 based on 4 consumer complaints alleging separation of an upper ball joint.complaints alleged an unexpected collapse in the front end and in some occasions the ball joint separation is alleged to have resulted in the wheel, brake rotor, and steering knuckle separating from the vehicle.since opening the PE, ODI has received 23 additional complaints related to ball joint separation. DaimlerChrysler has identified a wearout concern in the subject ball joints that is believed to occur after water intrusion evacuates the joint lubricant.DaimlerChrysler does not believe the condition poses an unreasonable risk to safety because the suspension design in the subject vehicles significantly reduces the likelihood of joint separation.over 99 percent of the failures are related to worn ball joints (e.g., noise complaints).DaimlerChrysler revised the repair procedure in August 2003 to allow the upper ball joints to be serviced separately from the upper control arm and reduce repair costs. DaimlerChrysler changed the supplier of the subject ball joints from TRW to new castle machining & forge for MY 2000 vehicles.MY 2000 Durango vehicles account for 25 of the 37 separation complaints.the upper ball joint was redesigned in MY 2003.this investigation has been upgraded to an engineering analysis to further assess the alleged defect in MY 2000-02 Durango vehicles.
