4A Vibration on Acceleration?

[glamosaurus]

When I put my 2.3 L base-squatch in 4A, I get a rhythmic pulsating vibration when accelerating over 30 mph. I can both feel it in the pedal and hear it. It's not loud, it's subtle, but noticeable. Is this normal for 4A?

It is normal, yes

Absolutely not willing to immediately write this off as normal - do you feel the vibration in the steering wheel at all?

No, really just the pedal and it's audible.

My 4A sounds and feels just like 2H or 4H.

I do have to press the accelerator a little more, as to be expected powering the front wheels.

But there is no other difference, and certainly no weird or abnormal noises.

I made an appt Friday morning with the dealership. We'll see what they say, I guess. :/

My 4A and 2H have no noticeable difference.

The only difference I noticed is torque steer in 4A. When I accelerate while making a turn. Its kinda hard to steer...

Thanks for your input, all. I've booked an appointment at the dealership Friday morning. We'll see what's up.

I have felt something similar. It's subtle enough that I thought it was my imagination, but it's only in 4A on moderate to hard accel. Mine is lifted, so I assumed it was extra cv joint angle pushing the cvs near thier limits. OP is your suspension all stock or lifted?

It's a stock sasquatch... 2-door base. 1300 miles on it. Haven't changed a thing.

Make sure your tire pressures are all the same or very close.

Thanks. According to the app, they're all the same. #shrug

My old 2021 SAS four door and my 2022 SAS two door both did/do this. I can feel it in my floorboard, and hear it in 4a. Being that it’s two for two, I lean towards normal tendency in the 4a mode. One was completely factory, the other is lifted.

I have asked this question twice on here now, as I get slight binding when in 4A even just turning the wheel a little.
It's not normal, from what I have gathered. If you're driving on dry roads and not losing traction, the 4A shouldn't be engaging.

Mine do not bind while turning
