Pulling to the left under acceleration when in 4A

[smj362]

Hi,
I was wondering if you might have the same/similar experience. When I am in 4A and accelerate and or under load (towing or going uphill) the truck ever so slightly wants to go to the left. Basically as soon as I give it a bit more throttle past maintaining cursing speed I can feel the steering wheel pulling to the left, which leads to constant counter steering to the right - annoying to say the least.
When in 2H I do not have that problem.

I have not mentioned that to my dealer yet, just wondering if others made the same / similar experience.

THX

I experience the same thing... I was kind of just thinking it was trq steer kind of effect.... cause of all the power haha

It’s normal if you have the Torsen front differential; you’re feeling the torque distributing between sides.

yes, it's torque steer and is normal

THX for all the responses.

Damn, in a prior life when I drive FWD I hated torque steer.

I’ve had my 2019 for about 3 months and thought I should at least verify 4 WD works. Today I put it in 4A with Advance track disabled. Apply moderate throttle and sure enough hard pull to the right. Does this mean I have the Torsten front diff? It’s a base model and original window sticker doesn’t specifically say it has Torsen, was it an option or just standard. I don’t think our 23 Raptor has it from what I’ve read on this forum.
I didn’t experiment anymore after that . Just remembered these threads about pulling in 4A, so thought I’d read up first.
I do have 35in Trail Grapplers and front leveling springs and 0 offset Methods.

Torsen was an add on to the base models. Unlikely that you have it, as the factory would have had to make a big mistake.

Kinda what I thought. I guess there must be another explanation for the pulling, but it seems to be a common occurrence. Doubtful I ever use 4A anyway, if it gonna be snowing, I’m taking my 2017 Superduty with 275K miles on it anyway. It’s a tank and know every little nuance about how it drives.
