What's wrong?
The steering gear on these 2025 trucks turns steering-wheel input into movement at the front wheels. Inside the gear, the sector shaft carries gear teeth that mesh with the rest of the steering gear assembly, so the truck responds when the driver turns the wheel.
On the recalled steering gears, the sector shaft was not heat-treated correctly. R.H. Sheppard traced the problem to heat-treat oven controls that let some shafts leave the batch with lower than required hardness. That weaker metal lets the gear teeth crack or fracture under steering load.
The warning sign is a popping sound when a tooth fractures. A truck with an affected gear cannot be identified by sight alone. The steering gear serial number must be inspected to tell whether the recalled gear is installed.

What's the safety risk?
Fractured steering gear teeth can cause a loss of steering control and increase the risk of a crash. A popping sound when steering is a warning sign that a tooth has fractured. If you hear it, stop using the truck and call the dealer for inspection. Repair is free at any franchised Peterbilt dealer.

What happens at the repair
At the dealer, a Peterbilt technician inspects the steering gear serial numbers to identify the units covered by recall 24V233. If the serial number shows a recalled gear, the technician replaces the steering gear. The recall covers parts and labor, so the dealer repair is free. PACCAR used its general reimbursement plan on file for this campaign. If you already paid for a steering gear repair tied to this recall, ask Peterbilt customer service or the dealer how to submit documentation under that plan.
