So I just got my turbo very running recently. But I'm having this odd problem. When I accel quickly, it pulls to the left. When I decel by using the motor, it pulls to the right. I do know the alignment is off, because the wheel isn't centered.

S5 TII, new motor mounts, TII stuff all the way back. I was told it was an S4 clutch type diff, but when I spin one wheel, the other wheel spins the opposite direction. It was making some odd noises when I spun it a bit too, so this makes me thing it could be the problem as well.


What do you think?

 

I think you should get an alignment.
You need it anyway, so even if it doesn't solve this issue, you're still ahead.

 

It's the torque of the motor putting your suspension in a new position. You can do anything about it. Welcome to power

 

I would have thought that it is the power of the motor, but this is much worse than my coupe. It was also a 91 tii, but jspec motor.

 

The problem will most likely be in the suspension/alignment. The only way this car doesn't track straight under power is if there is significant wheel spin. It should not pull to one side under deceleration. Take a good look at suspension and steering components. If they don't appear to be loose or damaged, take it in for an alignment. An alignment is only good if you don't have damaged parts.
