Noticed the LF wheel was dirty(oil) just after washing my truck. Called the Service Mgr. at Cav-Neub. and he said they were busy and short handed b/c of vacations, but bring it in and they will check it and order parts if needed. The first tech. back from lunch found the problem(axle shaft gasket), fixed it and I was back to the campsite within 2 hours. Excellent people that do excellent work at decent prices.
