Aug 4, 2014
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".
Consequence & remedy
Consequence: A spring that detaches from the hanger may result in a loss of control of the trailer, increasing the risk of a crash.
Remedy: Grand Design will notify owners, and dealers will replace the suspension bolts with ones that have a shorter thread depth, free of charge. The recall began in August 2014. Owners may contact Grand Design customer service at 1-574-825-9679. Grand Design's number for this recall is 910002.
