Trailer wheel seals are an integral part of a well operating trailer hub.  Trailer seals are installed in the back of the hub and seal to the section of the spindle that works to keep the wheel bearing grease or oil in a trailer hub, prevents water and dirt from entering the hubs which could cause bearing failure.  Therefore, it is extremely important to inspect your trailer seals regularly.  Grease or oil leaking past the seal seat or grease on the back of your trailer rim is a sign of a worn, torn, or old seal and must be fixed to prevent damage to the trailer hub or the trailer axle.
