Summary
Navistar is recall certain model year 2011 and 2012 international durastar and workstar commercial trucks manufactured from October 19, 2010, and February 3, 2011, equipped with gunite automatic slack adjusters. Due to an incomplete "knitting" of the iron at the time of casting, inadequate structural integrity of the slack adjuster housing can occur, which could cause the housing to break at the handle under normal operating loads.
Consequence
If the slack adjuster housing were to break, the wheel brake to which the slack adjuster is attached would no longer function, reducing braking capacity and, in some cases, causing the vehicle to pull to one side. Reduced braking performance and/or loss of steering control increases the risk of a crash.
Remedy
Navistar will notify owners and dealers will replace the subject slack adjusters free of charge. The safety recall is expected to begin on or about April 1, 2011. Owners may contact navistar at 1-800-448-7825.

Navistar's recall campaign number is 11504.OWNERS may also contact the national highway traffic safety administration's vehicle safety hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to http://www.safercar.gov.

Vehicles covered

As listed by NHTSA. A recall usually covers only some vehicles of each model and year, often a production date range.

Has your International been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A International dealer can also check your VIN. Recall repairs are free.
