Slight right pull under acceleration

MiamiBlue · Feb 28, 2025

I have a RHD (if it matters) and notice a slight pull to the right with medium to high acceleration. It's quite minor and I didn't realise at first, but subconsciously I think I've been adding a touch of left wheel steer to counteract with some heavy right foot. When coming off the accelerator it stops and goes back to how it was.

Is this a characteristic? (Little torque steer) Or do I need to investigate further? It's not causing any issues as it's so minor, just don't want to have an underlying problem.

Sounds like you just need an alignment

Higher unequal air pressures side to side could result in this.?....easy, and free!, to rule out........

I have a new US I4 (LHD)
On more sudden acceleration I notice a momentary slight pull in the steering to the left as the weight transfers.
Dealer said this is likely not an alignment issue and is just the result of having high torque.
I am not so sure.

Is this a case of "they all do that" or an alignment check being needed?

This is a good description of what I'm experiencing. It's just brief when you suddenly apply a lot of power, continued acceleration and it tracks straight. I'm noticing it less now, I think subconsciously I apply a small amount of opposite steering when I boot it.

I'll get an alignment check at 1000 miles when the initial service is done;
It's a minor issue, though I think it should not be happening.
Interested to hear if other I4 owners experience a slight steering pull to one side on acceleration bursts.

Never solved this. All four tyres pressure set correctly. Had a full geo. Resulted in some minor adjustments, but didn't change the slight steering change under hard acceleration. The person doing the geo tested the car afterwards and couldn't feel it. He suggested the front lifting (car squatting) under hard acceleration was making me think it was steering, but was an illusion.
Online research suggests it could be an issue with tyres (I still have the factory fit Goodyears with plenty of life) or there's a loose or worn suspension component that has some play that's being moved under different loading. (Should be unlikely on a low mileage new car).

Not sure what to do. Maybe go to a more specialised Geo place that can check it all over rather than just do an adjustment.

When I was breaking in my car, I would take it on the highway and do some pretty decent pulls to load the engine and then let it reduce speed in gear to help the pistons seat, etc. On acceleration, I would feel an odd sensation of the car trying to veer. I think now it may be a characteristic of the LSD. Not 100% sure though.
