Brief grinding noise when traversing a paved street transition

[snek]

Noticed something odd when driving over a slight dip in the road (transition between one street and another with a shallow dip
in road for drainage) with my 2.0 EB FX4 AWD Mav in 'normal' mode. When I approached this dip at 10mph at a 45 degree angle (
one wheel at a time transitioning through the dip) - I heard a brief grinding noise and vibration. This happened I think between when
the 2nd front wheel reached the dip and then the 1 rear wheel reached it (I hope that makes sense - this type of transition is real common
on asphalt streets where a small shallow concrete 'culvert' joins two asphalt sections). This happened the 1st time 2 days ago and caught
my attention. I happened to be on this same street yesterday and approached the same little dip slowly and again got the grinding
sound and vibration.

I guessing it was really nothing and by product of the AWD system engaging due to the momentary front to back wheel transition - but boy,
for a vehicle with 1400 miles on it, and my awareness on high for issues, this got my attention. Anyone else have this happen?

Keep on truckin!

Traction control kicking in, you’re hearing the ABS “grind”. Happens to me on my Ranger at times. Slow down a little on those spots or turn off TC.

Thanks 'Inthecabin' ! I will chill on the noise and vibration and slow up on these street transitions.
