The defect
Mack Trucks, Inc (Mack) is recalling certain 2024 Granite vehicles. The bearing journals may not be fully seated in the steering knuckle assembly, preventing the proper installation of the wheel end hub assembly.
The risk
An improperly installed wheel end hub assembly can leak oil, causing the axle spindles to loosen or fracture and increasing the risk of a crash.
