STEERING COLUMN WELD CRACKS

What NHTSA is examining

Early warning aggregate data submitted to nhtsa by freightliner suggests that a steering (ewr code 01) problem exists for the 2004 and 2005 century and columbia class vehicles.the count of field reports submitted for the first quarter of 2006 was significantly higher than the average of the previous 6 quarters for the aggregate steering data.further review of the ewr data foundfield reports that described steering column failures as a result of welds cracking or breaking.information received from freightliner details a number of steering columnfailures on the subject vehicles.these failures were the result of missing and cracked welds on the steering column assembly.an engineering analysis (ea) is warranted to determine if the weld failures in the steering column create a situation where the vehicle becomes difficult to steer or startles the driver presenting a safety risk.
