What's wrong?
The front steer drive axle on these 2024-2025 Kenworth T380, T480, 536, 537, and 548 trucks carries steering load at the front of the truck while supporting driven axle hardware. Inside each front hub, wheel bearings let the wheel turn smoothly under weight, steering force, and road shock. Those bearings need grease to keep metal surfaces separated and cool.
On trucks with the recalled axle serial numbers, the front hub has too little wheel bearing lubricant. With not enough grease, heat builds in the hub. The locking hardware can loosen, and the bearings can become damaged. Once that happens, the wheel end no longer holds its position the way it was designed to.
Owners can notice noise from the front wheel area, excessive steering play, or smoke coming from a front wheel. Those are warning signs that the hub or bearing area needs attention before the truck is driven farther.
Who's affected?
Covers Kenworth T380 and T480 trucks plus Peterbilt 536, 537, and 548 trucks from the 2024 and 2025 model years, all using the same FSD 10-23K drive axle.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Insufficient wheel-end lubrication can make the wheel hub overheat, raising fire risk, or lead to loss of vehicle control and crash risk. Treat noise, excessive steering play, or smoke from a front wheel as a reason to stop driving and call the dealer. Repair will be free at any franchised Kenworth dealer once available.
What should I do?
- Check your VIN to confirm your 2024-2025 Kenworth or Peterbilt truck is included in this recall.
- Wait for the owner notice before scheduling, since this recall is still listed as under development.
- Contact a franchised Kenworth dealer and reference recall number 24V903 when the repair opens.
- Ask the dealer to inspect the front axle wheel end, add bearing lubricant, and replace parts that prevent hub overheating or loss of control.
- Bring the recall notice if Kenworth has mailed one, or give the dealer your VIN when you call.
What happens at the repair
Once the final repair is available, a Kenworth technician will inspect the affected wheel end, repair it with new parts, and lubricate the wheel bearings as needed. The dealer repair will be free once it opens, with parts and labor covered under the recall. Kenworth uses the manufacturer's standard reimbursement plan for owners who paid for the same wheel end or bearing lubrication repair before the recall notice. Keep receipts and repair paperwork so the service desk or customer care team can review documented expenses.
