2023 F150 Tremor with 3,000 miles. When the truck is in 4A during acceleration there’s a subtle vibration in the gas pedal vs accelerating in 2wd. Anyone else experience this. It’s nothing dramatic or concerning (yet) but it definitely feels beyond the limit of “normal”.

I’m new to the F150 world and never noticed any vibration or difference in 2wd vs 4wd in my Tahoe during acceleration.

 

I feel a vibration in my pedal in 4a and 4hi. Probably 4L too.

 

Mine definitely gets a sound and feel in the wheel in 4hi. Hard to say if yours is "normal" without being in the truck with you. Near as I can remember all of my Fords have been similar.

 

I had this with my 2021 PB Lariat from new. It was a bad pinion bearing as it took 80 K km and 3 years to basically fail.

I don't know what to tell you as for me they refused to acknowledge it until it sounded like a 80's pickup truck with pinion whine, but from the front.

If there is no need to be in 4A, just go into RWD and see if vibration continues.
