Recall 10V634 covers 12,873 2007-2008 Peterbilt heavy trucks for driveline U-joint wear. Repair will be free at any franchised Peterbilt dealer once available.
Peterbilt is recalling 12,873 2007-2008 trucks, including 389, W900, and T800 models, because the extended lube universal joint on the inter-axle driveline can wear early and loosen or bind. If the driveline detaches from the axle, the truck can lose power or drop driveline parts into the roadway; the dealer repair will be free once available.

What's wrong?
The extended lube universal joint is the hinged connection between the inter-axle driveline and the drive axle on these 2007-2008 Peterbilt trucks. The driveline carries turning force between axles, and the universal joint lets that shaft keep spinning while the axle moves under load. Its bearing surfaces need lubrication so the joint turns smoothly instead of grinding or locking.
On affected trucks, lubrication breaks down and heat builds at the bearing surfaces. That wear happens earlier than designed. As the surfaces wear, the universal joint can loosen, bind, or stop moving freely. If the joint fails, the inter-axle driveline can separate from the axle instead of staying attached.
There is no warning sign before failure. A loose or binding driveline can be hard to distinguish from normal drivetrain noise, so the safe path is to treat VIN inclusion as the deciding factor, not wait for a sound or vibration.

The scope spans both model years and multiple truck models, all tied to the drive axle.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
If the driveline detaches from the axle, the truck can lose power and become disabled in the roadway. A dropped driveline also creates a roadway hazard and increases crash risk. Schedule the recall repair promptly. If the truck loses power, move out of traffic if you can and call for roadside help. Repair will be free at any franchised Peterbilt dealer once available.
What should I do?
- Check your VIN to confirm your 2007-2008 Peterbilt 389, W900, T800, T600, T2000, 357, 379, 386, 387, T660, 378, 385, or 388 is included in this recall.
- Contact a franchised Peterbilt dealer and ask whether the free driveline repair is open for your VIN.
- Reference recall number 10V634 when you call the dealer.
- Schedule the universal-joint repair that fixes premature driveline bearing wear before the driveline detaches from the axle.
- Avoid driving if the truck loses power, binds in the driveline, or shows driveline looseness; arrange service before returning it to the road.
What happens at the repair
Peterbilt is working with its supplier on the recall remedy. Once the repair is available, the dealer repair will be free. At the dealer, a Peterbilt technician will address the extended lube universal joint that connects the inter axle driveline to the drive axle, since worn bearing surfaces can let the joint loosen, bind, or fail. The source remedy says the safety recall was expected to begin during February 2011. Contact a Peterbilt dealer with your VIN and ask what repair procedure applies to this campaign.
