The defect
Grand Design RV, LLC (Grand Design) is recalling certain model year 2014 Momentum 355th, 380th, and 385th fifth wheel trailers manufactured June 24, 2013, to March 21, 2014 and built with 8,000lb capacity axles. The affected trailers may have been built with suspension bolts that can shear. These bolts connect the axle springs to the frame, and after they shear, the axle spring may detach from the frame hanger or "shackle".
The risk
A spring that detaches from the hanger may result in a loss of control of the trailer, increasing the risk of a crash.
