Somebody’s In Trouble!
Quite understandably most people in the world don’t ever consider the effects of poor (or in this case non existent) heat treating which is quite understandable. However as everybody in the industry knows bad heat treating can have catastrophic results. In this case Mack Truck recalled a few axles due to the fact that the parts completely missed being heat treated.
“Mack is recalling model year 2015 Pinnacle CXU tractors Meritor FF967 Non-Drive Front Steer Axles. Mack says the axles missed the heat treating operation during manufacturing, reducing their strength and possibly causing the axle beams to fracture. If an axle beam fractured, it could cause loss of vehicle control.”
