The defect
Mac Trailer Mfg., Inc. (Mac Trailer) is recalling certain 2017-2020 Dump trailers equipped with Ingersoll Smart-Steer self steer axles. The steering arm may detach from the steering knuckle during certain low-speed, high-side loading maneuvers.
The risk
A detached steering arm may cause a loss of steering control. In addition, attachment hardware may fall and become a road hazard. Both of these scenarios can increase the risk of a crash.
