Hope all is well once fixed. Not a typical problem. I had mine replaced under warranty as a precaution to the sound it made. Tunred out to be nothing but Cummins and dealer were excellent and took care of everything. Not a great location to get into change it for sure. Mechanic was back and forth from inside the coach to underneath. Said he got lots of walking in that day....lol.
