I live in NH and we needed to obtain a safety inspection on our new Greystone. We failed the inspection. The inspector found that all the wheels had axel grease in the wheels and around the electric brakes. Apparently, too much grease was injected into the bearing areas on all four wheels and then the bearings were WAY over tightened. The mechanic had to use a large pair of vice grips and work really hard to loosen the nuts. They should have been basically finger tightened. I had them start to try to clean up one wheel and they found that the bearing were scored, must have been really tight alright. Both our axel serial numbers were sequential so they were probably worked by the same individual. Heartland connected me to the people at Lippert who are trying to work this out. The magnets were covered with grease and we are not sure they can be cleaned up adequately. If your Greystone brakes are not working to well, better have a wheel popped off and see if there is grease everywhere in the brake drum. jim
