Three weeks ago, I bought a very slightly used 2022 Expedition Timberline with all available options and, for the most part, I love it. However, I just took a four-hour trip with a 6x12, 1,800 lb., tandem axle Interstate Loadrunner cargo trailer and noticed a very pronounced vibration (feels like the driveline; no transmission of the vibration to the steering wheel) when accelerating up a hill. It occurred when empty and with a piece of exercise equipment that only weighs about 200 lbs - well under the rated towing capacity.
The vibration does not occur when not towing, only when I have the trailer attached. It just happened yesterday, 12/29, so I haven't been to the dealer yet. Since it only occurs when towing and accelerating - even mildly - up a hill (not necessarily steep), I'm inclined to think it's a transmission related problem. Anyone else experienced this? Any ideas for isolating the cause are more than welcome. Cheers!
