We recently broke down in Newport, Oregon, the marina RV park.
Driving a Rexhall Rolls Air on a Spartan chassis, Cummins 6CTA8.3 engine. As I was checking the coach prior to pulling out on a Friday morning I noticed an oily film on the ground next to the left front tire. It seemed that the oil in that hub was a little low so I removed the red plug to check. When I reinserted the plug the plastic window broke and pushed into the hub cavity, dumping the hub oil.
I called Good Sam ERS, who contacted Newport Diesel, who called us back. Newport Diesel said it would be Monday before they could obtain and install a new hub seal. However, one of their guys showed up in the early afternoon and removed the hub cap to take it back to the shop where they would replace the plastic window. Late that same afternoon another guy returned with the rebuilt hub cap and we were ready to go by 5 pm. We paid for labor and parts; Good Sam ERS paid for the service calls.
