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.
