Summary
Wilson trailer is recalling certain model year 2011 grain trailers manufactured from October 15, 2010, through January 31, 2011, and 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
Slack adjusters with this flow notch could crack under normal braking conditions causing loss of braking which could result in a vehicle crash.
Remedy
Wilson trailer will notify owners the slack adjusters will be replaced free of charge. The safety recall began on October 10, 2011. Owners may contact accuride at 1-812-962-5000 or wison trailer at 1-712-252-6477.

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 Wilson 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 Wilson dealer can also check your VIN. Recall repairs are free.
