What's wrong?
The hex flange lock nuts on the 2021-2022 Chevrolet 4500HD, 4500XD, 5500HD, 5500XD, and 6500HD are the heavy nuts used at suspension and steering joints. A lock nut is supposed to hold clamped joint hardware tight after installation, so the connected parts stay in position as the truck carries weight, turns, and moves over road impacts. In these joints, that clamping force matters for steady steering and suspension alignment.
On affected trucks, certain nuts were not formed and heat treated correctly by the supplier. Heat treatment sets the metal's hardness and strength. If that process is wrong, the nut can be too weak for the loads at the joint and can break. Once a nut breaks, the joint it was holding loses clamping force, which changes how the truck handles.
Drivers can notice degraded vehicle handling before the nut failure is found. If the truck feels less stable, harder to keep in line, or different during steering, treat that as the warning sign.

What's the safety risk?
Broken hex flange lock nuts can lose tension, causing steering instability and increasing the risk of a crash. If the vehicle starts to handle worse than normal, slow down, avoid sharp maneuvers, and arrange service soon. Repair will be free at any franchised Chevrolet dealer once available.
What should I do?
- Check your VIN to confirm your 2021-2022 Chevrolet 4500HD, 5500XD, 4500XD, 6500HD, or 5500HD is included in this recall.
- Watch for Chevrolet's owner letter before scheduling the final dealer repair.
- Contact a franchised Chevrolet dealer to ask whether the free hex flange lock nut replacement that restores tension in the suspension and steering joints is open for your VIN.
- Bring the recall notice if Chevrolet mailed one, or reference recall number 22V874 when you call.
- Drive cautiously until the repair is complete, and stop using the vehicle if the steering feels unstable.
What happens at the repair
At the dealer, a Chevrolet technician will inspect the suspension and steering joint hardware and replace the hex flange lock nuts that need replacement. The final dealer repair will be free once available, with parts and labor covered under the recall. Out-of-pocket repairs already paid are handled through the existing warranty, not through a separate reimbursement program, because the covered vehicles are under warranty. Ask the service desk how warranty coverage applies if you have prior repair paperwork.

Frequently asked questions
What is recall 22V874?
Recall 22V874 covers 5,861 2021-2022 Chevrolet 4500HD, 5500XD, 4500XD, 6500HD, and 5500HD vehicles with hex flange lock nuts in suspension and steering joints that were improperly heat treated. Broken nuts can reduce tension, cause steering instability, and increase crash risk.
What should I do if my 2021-2022 Chevrolet 4500HD, 5500XD, 4500XD, 6500HD, or 5500HD is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 22V874. If it is, contact a franchised Chevrolet dealer and ask for the hex flange lock nut inspection and replacement. Reference recall number 22V874 or GM recall N222391080 when you call.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to fix the safety defect at no cost, and Chevrolet dealers will replace the affected hex flange lock nuts as needed free of charge. Parts and labor are covered for included vehicles.
What is the safety risk?
The safety risk is steering instability. If a hex flange lock nut breaks in a suspension or steering joint, the joint can lose tension. GM says that condition increases the risk of a crash, so included vehicles need the dealer repair.
