On return trip I sensed (with ears and seat) a hi frequency rumble at/about 47 MPH. Subsided above 47 and did not appear below (for the most part). Occurred both while accelerating and decelerating. Did not feel through the steering wheel, but felt through the cab and in the seat. Truck handled normally throughout speed range. Thought maybe motor or transmission at first, but took it out of gear and let it coast through the speed range and it occurred as well. Now thinking bad tire or rear axle. Once stopped at destination rear/passenger side hub cap was warm (not hot) while all others were ambient temp. Anyone able to refine my troubleshooting and give me some ideas? | | |
