What's wrong?
The rear axle shafts on the 2014 International Prostar carry engine power from the rear axle differential out to the wheel ends. The splines are the machined teeth at the inner end of each shaft, and they lock into the differential side gears so power moves through the axle without slipping. On trucks with feature code 14GXP 6X2 rear axles, 'R' hubs, and Dual Track rear axles, that spline engagement is the critical fit.
In the recalled trucks, the axle shafts installed in production are the wrong length. Because the shafts do not match the axle setup, the splines only reach partway into the side gears instead of seating across the full designed contact area. That puts drive torque through a partial connection and leaves the axle assembly outside its intended design.
There is no warning sign before failure. A driver should not expect a dashboard light, noise, or feel change to confirm the axle shaft problem before the dealer inspects and repairs it.

A matching 2014 International Prostar does not confirm inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Partial engagement can damage axle shaft splines or side gears. If those parts fail, the truck can lose power to the drive wheels and stall on the roadway, increasing crash risk. Schedule service promptly and use caution until repaired. Repair will be free at any franchised International dealer once available.
What should I do?
- Check your VIN to confirm your 2014 International Prostar is included in this recall.
- Contact a franchised International dealer and ask whether the free axle-hub and axle-shaft repair is ready for your truck.
- Reference recall number 14V107 when you call so the dealer can find the correct repair instructions.
- Schedule the axle-hub and axle-shaft replacement that fixes the partially engaged rear-axle splines and protects drive-wheel power.
- Bring Navistar's owner notice mailed on March 18, 2014 if you have it.
What happens at the repair
At the dealer, an International technician replaces the incorrect wheel hubs and axle shafts with the correct parts. The technician also checks the rear axle differential side gears and replaces any damaged side gears found during the repair. International listed the recall repair as free of charge, with the owner notice process beginning on March 18, 2014. If the dealer still has to order parts or confirm campaign handling for your VIN, parts and labor remain covered once the repair is available.
