What's wrong?
The wheel hub is the metal assembly that supports the wheel and lets it rotate on the axle. On these 2025 Fccc trucks, buses, cabs, and chassis, the hub fasteners and retainer washer help hold the wheel end tight so the wheel stays aligned under load.
NHTSA campaign 24V393 identifies two related assembly problems. Some preset hubs were missing a snap ring, and some conventional 4-piece fastener hubs had retainer washer locking tabs that were not bent inward as required. Either condition lets the hub develop excessive end play, which means the wheel end has too much movement. If the fasteners loosen enough, the wheel can detach and the driver can lose vehicle control.
The listed warning signs are anti-lock braking system diagnostic trouble codes, which are stored fault messages for the ABS, and hub oil leakage from a failed hub seal. If either appears, treat it as a wheel-end warning and contact a Fccc dealer.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific vehicle is included.
What's the safety risk?
Excessive wheel endplay can lead to loss of vehicle control and increase the risk of a crash. Watch for ABS diagnostic trouble codes or hub oil leakage, and schedule the recall inspection promptly if your VIN is included. Repair is free at any franchised Fccc dealer.
What should I do?
- Check your VIN to confirm your 2025 Fccc vehicle is included in this recall.
- Contact a franchised Fccc dealer to schedule the free hub-nut retaining-system inspection and repair that secures the wheel hub fasteners.
- Bring the recall notice if DTNA mailed one. If not, reference recall number 24V393 and DTNA recall F1002 when you call.
- Ask the dealer whether the vehicle should stay parked until inspection, especially if it is used for passenger or commercial service.
- Drive cautiously until the repair is complete, since loose wheel hub fasteners can lead to wheel separation and loss of vehicle control.
What happens at the repair
At the dealer, an Fccc technician inspects the hub nut retaining system, wheel end, and axle components. Any covered parts that need replacement are replaced free of charge under the recall, and parts and labor are covered. If you've already paid out of pocket for a related hub, wheel end, or axle repair, Fccc's reimbursement instructions direct owners to seek reimbursement through authorized dealers. Bring repair orders, receipts, and any owner letter paperwork to the service desk so the dealer can review the claim under the recall.
