Be careful with the duralube wheel bearings. About 6,000 miles ago I added grease to my Rockwood 2703WS very carefully following the instructions in the manual. I went in to the dealer to have the bearings checked and repacked at 12,000 miles and found that 3 of the 4 bearings had leaked grease requiring replacement of all 4 brake assemblies. The service manager suggested putting in 2 pumps of grease every other year between bearing repacks.
