Summary
On certain trailers equipped with sealco spring brake control valve assemblies incorporated in arvinmeritor axles, part nos. 110700 and 110800, there is a recessed area on top of the valve in which a brass guide pin fits down inside the body of the valve and is held in place by a steel snap ring. The recessed area allows accumulation of water, dirt, and/or chemicals to build up behind the snap ring to the point where it will no longer contain the guide pin resulting in a failure of the air valve.
Consequence
Failure of the valve in an empty or lightly loaded trailer while the vehicle is in motion could result in a hard application of the spring brakes, possibly locking up the trailer wheels and resulting in a vehicle crash.
Remedy
Sealco will provide a repair kit and installation instructions to customers free of charge. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact sealco at 602-253-1007 or spector at 1-570-429-2510.
Notes
Also, customers can contact the national highway traffic safety administration's auto safety hotline at 1-888-dash-2-dot (1-888-327-4236).

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 Spec TEC 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 Spec TEC dealer can also check your VIN. Recall repairs are free.
