No Lock Stearing issue
I've got a 2007 Pontiac G6 GT When going uphill at approx. 65 MPH in a left hand turn the steering will suddenly pull hard left. If I back off the accelerator even slightly it frees up. it also feels like the rearend is coming around to the right as if on a slick road. This began after having a 4 wheel alignment. I have taken the vehicle back and had them check again and they could find nothing out of place. They checked the motor mounts for wear thinking it was possibly Torque steering but they are fine and it never happens turning right or going straight. It has happened on a flat roadway turning left and hitting a small bump at approx 50 MPH.
Thanks in advance
