Recall 16V929 affects 200 2012-2017 Mack Granite (Gu), Pinnacle, and Titan (Td) trucks for overloaded front wheel hubs. Free repair at a franchised Mack dealer.
Mack is recalling 200 2012-2017 Granite (Gu), Pinnacle (Chu), Pinnacle (Cxu), and Titan (Td) trucks because the front wheel hubs cannot support the front axle's gross axle weight rating. Overloaded hubs can fail early, let the front hub assembly separate from the axle, and increase crash risk; Mack dealers will complete the free repair.

What's wrong?
The front wheel hub on these 2012-2017 Mack Pinnacle (Cxu), Granite (Gu), Pinnacle (Chu), and Titan (Td) trucks supports the wheel and lets it rotate around the front axle. It also keeps the wheel end aligned so the brake and anti-lock braking system (ABS) parts stay in the correct position. On a heavy truck, the hub has to match the gross axle weight rating, which is the maximum weight the front axle is designed to carry.
On affected trucks, the installed front hubs are not rated to support the full front axle load. The filing says the required build restrictions were not in place, so trucks left the factory with hub assemblies below the needed rating. Under normal service loads, that mismatch can create wheel end play, damage the hub assembly, and lead to wheel separation if the problem is not found.
Owners or shops can catch this during required wheel end play inspections. The ABS malfunction light is another warning sign, because the ABS sensor can lose contact with the tone ring as the spacing changes.

What's the safety risk?
Overloaded front wheel hubs can fail early, damaging the hubs, bearings, and related parts. If the front hub assembly separates from the axle, the driver can lose control or parts can fall onto the road, increasing crash risk. Watch for an ABS malfunction light and have wheel end play inspections handled promptly. Repair is free at any franchised Mack dealer.
What should I do?
- Check your VIN to confirm your 2012-2017 Mack Pinnacle (Cxu), Granite (Gu), Pinnacle (Chu), or Titan (Td) truck is included in this recall.
- Contact a franchised Mack dealer to schedule the free front-hub-assembly replacement for hubs that do not support the front axle weight rating.
- Bring the recall notice if Mack mailed one. If not, reference recall number 16V929 and Mack recall SC0406 when you call.
- Avoid overloading the front axle and drive cautiously until the repair is complete.
What happens at the repair
At the dealer, a Mack technician replaces the front wheel hub assemblies covered by recall 16V929. The parts and labor are free under the recall. Mack's filing says a reimbursement plan exists, so owners who already paid for a related front hub repair before the recall notice should ask Mack customer service or the dealer service desk how to submit repair paperwork for reimbursement.
