Wife in Ga got warning light. Anyone know what it is?

[Brent Wahl]

Wife is 3 hours away in Ga and our 2020 Expedition Max Platinum threw a warning light.

Anyone know the risk of driving with it and what it means?

She was off roading and didn't want to tell you.

I hope she did not turn the wheel while that light was on.

Why?

Why?

Rear driveline is “locked”. Creates wheel hop as both tires spin at the same speed.
In my own experience, my wife did the same in another car, it was fine. No issues.

Perhaps. But 90% of the time the tire breaks traction first.

Damage 10% of the time is still pretty high. Another possibility is that the clutches in the ELSD will just start slipping.

I’m not advocating to drive with it locked. His wife had it on for a short period, low risk of severe damage, especially if not making hard turns at slow speeds.
