Noob expedition owner. Just want to make sure I am not doing anything wrong w.r.t 4WD / AWD
First question:
My 2022 expedition makes some weird sounds from the transmission when I am running on 4H at slow speeds. Is this normal ? I had just returned from a snow mountain trip to Tahoe (360 miles round tip). I had switched from 2H to 4H when I started encountering snow going uphill on the mountain. I left it at 4H even while coming back and back to regular roads (Bay Area). And now when driving slow on residential roads in bay area, the 4H is making weird sounds and there are a few jerky movements.
Second question:
Want to confirm that my following understanding is correct
4H : Use this to force vehicle to run power to all 4 wheels ALL the time
4A : Vehicle computer decides whether to power 2 wheels or 4 wheels. Vehicle computer may decide to run at 2 wheel drive when road conditions allow it.
4L : To be used only at very low speeds and to be used for say pulling the vehicle out of a ditch or when stuck on snow/sand
