Developed a Driveline Growl
Just got this thing. Only 18K miles on it and on the way home today it developed a mild driveline growl, almost a vibration. Not related to wheels/tires. It's engine, something on the engine [not AC as I turned that off] or in the drivetrain immediately behind the engine. Since I can hear it as well as feel it both through the steering wheel and my a$$ I am pretty sure it is something ahead of the drivers' position. It is related to rpm and disappears about 2Krpm or so.
4.0L, 5 Speed Auto, 4x4.
Any known issues? Otherwise, obviously I'll need to just take it in.
Truck runs and drives fine but it's one of those sounds / feelings that just makes you think this can't be good . . .
