TRW Automotive is recalling 2,586 IGEN3 intermediate steering columns which were shipped to certain vehicle manufacturers between April 21 and May 26, 2009, for use as original and/or replacement equipment on heavy trucks.
The weld around the IGEN3 steering shaft tube that secures the spline tube to the intermediate tube may be mislocated (i.e., not fully over the seam created when the tubes are pressed together.) Mislocated welds may result in torsional and axial strength falling below acceptable levels. This condition could result in separation of the steering column, loss of steering control and a vehicle crash without warning.
Each vehicle manufacturer will provide a remedy plan and notification schedule. The affected vehicles will be repaired without charge to the owners. The recall began on July 2, 2009.
Owners may contact their vehicle manufacturer or TRW Commercial Steering Systems at 1-765-429-1768.
