Mack recall: Steering
What is wrong
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.
What could happen
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.
The fix
Hendrickson will inspect and replace the steering knuckle assembly as necessary, free of charge. Owner notification letters were mailed February 2, 2024. Owners may contact Mack customer service at 1-800-866-1177. Mack's number for this recall is SC0456.
