NHTSA's summary

As NHTSA's Office of Defects Investigation wrote it for Engineering Analysis EA03-019.

GM'S LETTER TO NHTSA DATED DECEMBER 11, 2003, EXPANDS ITS ORIGINAL RECALL (NHTSA 02V286) TO INCLUDE CERTAIN W-BODY VEHICLES: 96-97 OLDS CUTLASS SUPREME; 98 OLDS INTRIGUE; 97-98 OLDS CUTLASS; 97-98 CHEVY LUMINA, MONTE CARLO AND MALIBU; 96 PONTIAC GRAND PRIX; AND 96-98 BUICK REGAL.THE NUMBER OF VEHICLES RECALLED IS 750,283.

GM DETERMINED THAT FAILURE OF THE RACK AND PINION IS RELATED TO DAMAGE OF THE LOWER PINION BEARING AND THE LEVEL OF THE PINION BEARING PRE-LOAD SPRING FORCE.GM STATES, HIGHER RACK PRE-LOAD SPRING FORCE (133 LB.) IS THE DESIGN CHARACTERISTIC MOST CLOSELY ASSOCIATED WITH HIGHER BEARING DAMAGE RATES IN MOST OF THE VEHICLE APPLICATIONS THAT USED THE GENERAL BEARING COMPANY (GBC) BEARING.ALL OF THE VEHICLES COVERED IN THE EXPANDED RECALL HAVE THE 133 LB SPRING FORCE.THE 96 LUMINA/MONTE CARLO AND 97-98 CENTURY W-BODY VEHICLES INCLUDED IN THIS INVESTIGATION UTILIZE A LOWER SPRING FORCE AND ARE NOT INCLUDED IN THE RECALL.

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.
