my 2016 Ford Expedition XLT 4x4 just turned 70,000 miles on my way back from visiting family in Ohio. I noticed that there is a hum in the front end. There's a little vibration that makes me think of a bad bearing, or the front 4x4 hub is engaged.
Even though the truck has 70,000 miles, I'm kind of surprised that it could have a bad wheel hub. I'm wondering if the front 4x4 hub still uses vacuum to keep it disconnected. On my trip, I hit a large chunk of rubber with the right front. I'm wondering if I could have damaged something that's causing the 4x4 hub to engage.
I haven't jacked the front end up yet to try and figure out what the problem could be. I started wondering if the 4x4 hub could be engaged, and figured I'd try to get some input before I jack it up and start looking around.
