Navistar Recalls More Than 9,500 Trucks

Truck maker Navistar Inc. told the National Highway Traffic Safety Administration it is recalling 9,578 ProStar and TranStar trucks because of problems with S-cam tubes on steer-axle brake assemblies made by Meritor Inc.

NHTSA posted a letter saying the trucks were made from August 2011 through July 2012 and sold in the United States, Canada and into export markets.

“The brake S-cam tube bracket assemblies on steer axles may exhibit fractures between the wing bracket and the tube steel when mounted to stamped spiders,” said a letter from R.L. Van Laar, Navistar’s compliance manager. A brake spider is the foundation for brake assemblies.

Navistar said it will notify truck owners by mail by Aug. 23.
