2024 Lincoln Navigator tire problems

I can't imagine "unplugging" the shock absorbers would work without wreaking havoc to the vehicle in terms of warnings and whatever system defaults may be in place.

For those who may not understand the working theory behind these types of shock absorbers, here is an AI clip...

Magnetic fluid shock absorbers, also known as magnetorheological dampers, use a special fluid that changes its viscosity in response to a magnetic field. When an electric current is applied, the magnetic particles in the fluid align, thickening it and allowing the shock absorber to adjust its stiffness almost instantly, improving ride comfort and handling.

Unplugging them in theory would likely leave the shock absorbers in a 'soft' state as the whole design theory relies on 'stiffening' the shocks on demand by magnetic force to the fluid inside the shock and depending upon the particular design, possibly affecting any variable valving inside the shock.

I don't think Navigators use magnetorheological dampers; GM vehicles (and whoever they licence them to) do though, and it's a superior design. I have two other vehicles with electronically adjustable shock absorbers, and in one of them disconnecting makes them soft, while in the other, conversely, stiff. So it's hard to say off the cuff.

In any case, vibration that appears at a certain speed is extremely unlikely to be related to shock absorbers. Testing that would be a wasted effort.

It would be great if there is a way to turn off/disable/stop the forward looking cameras or sensors from seeing the approaching road surface and therefore adjusting the ride (if that could cause the "vibration").
