Recall 11V167 affects 33 2011-2012 International Durastar and Workstar trucks for slack adjuster housings that can break. Free repair at any franchised International dealer.
International is recalling 33 2011-2012 Durastar and Workstar commercial trucks equipped with Gunite automatic slack adjusters because the slack adjuster housing can break under normal operating loads. A broken housing leaves that wheel brake inoperative, reduces braking capacity, and can cause the truck to pull to one side; the dealer repair will be free once International makes it available.

What's wrong?
The automatic slack adjuster on 2011-2012 International Durastar and Workstar trucks is part of the air-brake linkage. Its job is to keep the brake shoes the right distance from the brake drum as the lining wears. That adjustment helps the air-brake system apply force consistently when the driver presses the brake pedal.
These trucks were built with Gunite automatic slack adjusters that have a casting defect in the iron housing. During casting, the iron did not fully knit together, so the housing lacks the structural strength it was designed to have. Under normal operating loads, the housing can break at the handle instead of carrying the load through the brake linkage.
There is no warning sign before failure. The filing does not describe a noise, warning light, pedal change, or inspection clue that an owner would notice before the slack adjuster housing breaks.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific truck.
What's the safety risk?
If the slack adjuster housing breaks, the attached wheel brake no longer functions. That reduces braking capacity and can make the vehicle pull to one side, increasing crash risk through reduced braking performance or loss of steering control. Schedule the recall repair promptly and leave extra stopping room until it is complete. Repair will be free at any franchised International dealer once available.
What should I do?
- Check your VIN to confirm your 2011-2012 International Durastar or Workstar is included in this recall.
- Watch for International's owner notice, which was mailed on April 21, 2011.
- Contact a franchised International dealer and ask whether the free slack-adjuster replacement that restores the affected wheel brake is open for recall number 11V167.
- Bring the recall notice if you have it when you visit the dealer.
- Drive cautiously until the repair is complete. Leave extra stopping distance and pull over if braking feels uneven.
What happens at the repair
Once available, an International technician will replace the affected Gunite automatic slack adjusters. The repair addresses slack adjuster housings that can break at the handle under normal operating loads because the iron casting lacks enough structural integrity. The filing says Navistar planned owner notification around April 1, 2011. The final dealer repair will be free once available, with replacement parts and labor covered under recall 11V167.
