Owner report 10897440 · 2016-08-21 (August 21, 2016)
AFTER READING ON THE GRAND DESIGN OWNERS FORUM ABOUT LEAKING GREASE SEALS ON THE WHEELS, I DECIDED TO DO AN INSPECTION OF MY BRAKES. I HAVE PUT ONLY 500 MILES ON MY TRAILER SINCE TAKING DELIVERY ON JUNE 8, 2016. I ASSUME THAT THE TRAILER WAS DELIVERED TO OREGON BY TOWING IT FROM THE FACTORY. I REMOVED THE RIGHT FRONT BRAKE DRUM AND SURE ENOUGH FOUND A FAILED GREASE SEAL AND GLOBS OF WHEEL BEARING GREASE ON THE DRUM, BRAKE SHOES AND MAGNET.
