Took the Cat down to have trailer bearings repacked and wheel alignment checked. Spring Works, a local trailer company, pulled the bearings and cleaned them and the races, replaced the seals. They said the bearings and grease were the cleanest they had seen on a trailer that had not been serviced for 3 years and with the miles I had put on it. They said”do not use the bearing buddies to put grease in the hubs.” I said I think I have heard that somewhere before and I never have. In short everything was in perfect order. Martin.
