    I’ve noticed an issue that I thought would go away when the alignment was fixed but it didn’t. Basically when I go from a stand still and press the gas heavier then normal the steering wheel will steer right and then straighten out when I take my hands off of it. Almost like toque steer in a front wheel drive car. I’ve done this on both flat and slanted surfaces and there was no difference, it did the same thing. It’s not really an issue for me to worry about as of now, but I’m curious to what it could be. Also the car, with the alignment done, still pulls to the right a little bit when I remove my hands from the wheel. Any ideas?

    I use firestone's lifetime alignment and have had to make them redo it a couple of times. Can you post a picture of the printout?

    If the alignment is indeed correct, I'm not 100% sure. It could be clutches in the front diff are worn causing torque vectoring to one side. I would think, if that is the case, the left wheel is getting more torque and pushing your truck to the right. I feel that this is unlikely though.

    If it is alignment, then I would suspect the right wheel is pulling to the right and would have incorrect camber or toe in on that side.

    I thought toque steer only affected the Canadian models.


    Check for a dragging brake. Check the wheel temps after a drive. They should match left to right.

    Here’s a picture of the alignment paper.

    interesting you say that, I do hear a squeaking noise when I’m driving coming from the wheels that I expected to be one of the brakes rubbing but i think it would be odd if that’s the reason why no mater what angle surface I’m on, my steering wheel pulls to the right from a stand still.

    Damn, good catch. Didn't even think of that. And, it makes sense.

    The sticking caliper (most likely front right in this case) would bind after coming to a stop.

    Applying the brakes would push the pistons into the back of the pad and force the caliper to slide on the carrier pins. If the right side piston is not returning into its bore, or the caliper is not sliding freely on the two carrier pins, it would make sense that it would slow the rotation of that wheel--dragging the car to the right.

    If it is as sever as you describe, and the electronics on our trucks are so sensitive, I would wonder why there isn't a wheel speed or and code...

    Most troubling we haven't solved the toque steer.
