These trailers are equipped with axle assemblies using hubs that affix the tire/wheel assembly to the hub with threaded studs and lug nuts. The lug stud bolts may have crystallized and may pop or twist off with little resistance.
The risk
This condition can result in unexpected separation of the wheel from the axle, and result in a vehicle accident.
The remedy
Dealers will replace the hub and drum assemblies with new threaded studs and lug nuts.
