WASHINGTON - Daimler Trucks North America is recalling 352 MY 2010 Freightliner Cascadia trucks equipped with optional Sheppard HD94 steering gears. 

The trucks involved in the recall were manufactured between May 20, 2009 and Jan. 29, 2010. 

Restraining washer locking tabs may not have been seated into the Pitman arm retainer notches during assembly. Incomplete installation of the Pitman arm retaining mechanism may allow unthreading of the retainer. Disengagement of the Pitman arm from the steering box may result in loss of steering. This poses a safety risk, the National Highway Traffic Safety Administration said. 

Dealers will inspect the recalled trucks to ensure the Pitman arm retainer is properly torqued and the restraining washer is properly installed with locking tabs seated in notches of the retainer. There will be no charge for this service. 

The safety recall is expected to begin by April 23. Truck owners can reach Daimler Trucks at (800) 547-0712.
