Recall 77V-121: 1976–1977 Freightliner Freightliner
FREIGHTLINER CORP. recall for wheels, reported to NHTSA on Aug 12, 1977, covering about 163 vehicles.
The problem
On the involved vehicles, cracks may develop at the base of the inner wheel bearing cup and propagate circumferentially around the barrel of the hub. A fracture between the inner hub end and the flange portion of the hub could eventually develop. Failure could occur causing hub separation. Continued operation after hub separation has occurred could result in lock-up of brake assembly, excessive heat generation due to brake lining to drum contact, and progressive damage to the hub, causing the separated hub with the wheel and tire to disengage from the truck.
The fix
Dealer will replace the aluminum hubs with steel hub, cup and stud assemblies, without charge to owner.
