What's wrong?
On a 2011 International Prostar, the driveline sends engine power through the transmission and driveshaft to the rear axle. The center support bearing holds part of that rotating driveline in the correct position. A rubber isolator sits around the bearing to absorb vibration and keep the bearing steady inside its mounting bracket.
In trucks covered by this recall, the bearing mount is in the wrong location for the driveline setup. That placement puts the rubber isolator where it deteriorates instead of holding the bearing securely. As the rubber breaks down, the bearing loses support, and the driveline can move outside its intended path. If the support fails, the driveline can separate while the truck is moving.
There is no warning sign before failure. The recall describes driveline separation without warning, so a truck that feels normal is still included if its VIN falls under campaign 10V630.
