2016 GRAND DESIGN MOMENTUM Wheels Problems

MY 2016 GRAND DESIGN MOMENTUM 327M USES LIPPERT AXLES. THREE OF THE FOUR GREASE SEALS LEAKED AND WERE FOUND DURING A STATE INSPECTION. THE GREASE CONTAMINATED THE BRAKES. A 2018 STATE INSPECTION AGAIN SHOWED FAILED GREASE SEALS AND CONTAMINATED BRAKES. THE WARRANTY COVERED THE COST ON THE 2016 INSPECTION, BUT NOT THE 2018 INSPECTION. I CONTACTED GRAND DESIGN REGARDING THE ISSUE. I WAS TOLD THAT NEW MODELS WERE BUILT USING DEXTER AXLES TO SOLVE THE PROBLEM. AS A REGISTERED PROFESSIONAL MECHANICAL ENGINEER, I AM CONCERNED THAT I HAVE A CAMPER WITH A 16,000+LB GVWR THAT HAS LEAKING SEALS AND POSSIBLY FAILED BRAKES. I REQUESTED NEW AXLES, BUT GRAND DESIGN DID NOT RESPOND. I AM REQUESTING THAT NHTSA ISSUE A RECALL TO REQUIRE THAT THE ISSUE IS FIXED BEFORE IT CAUSES AN ACCIDENT. I FOUND A CLASS ACTION SUIT ALREADY FILED TO ADDRESS THE ISSUE SO IT IS A COMMON PROBLEM....
