Check against the official notice below — it lists the full affected range.
Mack Trucks is recalling certain 2011-2012 model year CHU, CXU, GU, LEU, and MRU trucks manufactured between October 15, 2010, and January 31, 2011, that are equipped with Gunite automatic slack adjusters. The slack adjusters can crack under normal braking conditions due to incomplete iron bonding during the casting process, which compromises the structural integrity of the housing and could cause it to break at the handle during normal operation.
If the slack adjuster breaks, the truck could lose braking ability and potentially crash. Mack Trucks will notify owners, and dealers will replace the defective slack adjusters at no charge. Affected owners should contact Mack Trucks at 1-800-528-6586.
