NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Preliminary Evaluation PE03-032.
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.
Vehicles and equipment listed for this investigation

What an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
