Odd “vibration” during partial throttle deceleration

[chris51080]

I’m in the middle of another cross country road trip, and will end up visiting the dealer when I get home. That said, on the highway, when I let off the gas partially, I feel a bit of a vibration in the pedal/floorboard as well as a slight change of noise.

If I let off the gas completely, it goes away. It also goes away once I get give it enough gas to begin accelerating.

Any thoughts on this?

Have the dealer look into the pinion bearing in the front differential. Mine started failing around 4k miles. Diff was rebuilt at 13k miles.

i had a grinding sensation/vibration in the pedals that you could also feel in the steering wheel a bit. it seemed to be there only on throttle but if you barely put your foot on the gas when in motion you could still feel it. dealer swapped out both IWEs up front and it went away. 24k miles
