This morning we had to scurry out the door to get our Murano into Al West Nissan to have the humming noise investigated. While it might have been a transmission issue, we lucked out. It was only the left front wheel bearing and only about $450 to repair. In at 8 AM done by 9:30. So we only lost a couple if hours on the road.
Met the owner (Al West) and the service manager (Gary McKee) and the Service Advisor (David Cliburn). Gary Mc was very chatty and offered a number of good suggestions of things to see on our trip.
Ready to continue on the road trip!
