    Possible Power Steering Issue

    I only notice this when I turn the wheel while not moving or while inching forward or back because its too subtle to notice otherwise. When turning the wheel left of center, I get a vibration. Very subtle. I feel it in the wheel and my left foot even feels it while its resting on the dead pedal. Right of center? Nothing. Smooth.

    Tried to check the ps fluid but I didn't see any indicators on the tank that showed what level it should be filled to. Did I miss it? How high should the ps fluid come? Is that even the problem? Just over 58,300 miles and i have a bad habit of treating my daily commute like a racetrack. I corner hard. What do you guys think? Thanks.

    Ps fluid is on the little stick when you take the cap off. Just like checking engine oil. It could be normal we have a wide front tire it could just be how it is when not moving. I all ways move be for turning the wheel it hard on every thing other wise. But start by checking the ps fluid.

    Re: Possible Power Steering Issue

    Ill check tomorrow. And I am aware that its not good to turn the wheel unless you're moving. That's why I tried to inch forward/back while duplicating it. Although admittedly I did it while on the brakes a couple of times. Ill check the fluid before I take off for work in the morning. Thanks.

    If the fluid is ok try it in some grass and see if it still is doing it.

    Sounds good. Also, check ps fluid before starting the car in the morning right?

    Most cars you can also check hot. There are two lines one hot and one cold.

    Re: Possible Power Steering Issue

    The ps cap has a "zone" where the fluid is supposed to be. It's a little square with the word "hot" on it. Just did a bunch of driving and checked. It's not clear to me what my level is.

    ----------

    Never mind I used the back and I can tell I'm good. Now I have to figure out what else it could be.

    Try parking on grass now and turning the wheel and see if it still feels the same. That way you know it was just not the blacktop holding the wheels from turning free.

    Re: Possible Power Steering Issue

    As soon as I checked the fluid I did that. Didn't get a chance to post until now. Unfortunately, same deal on the grass.

    I called my dealer and said I had a problem with my car that I could duplicate at the moment. Asked if I could come in and have one of the guys experience the issue and then I'd make an appointment to get it fixed. Told them they don't even have to drive it, just sit in the lot and turn the wheel. They said they absolutely couldn't spare anyone at all. They were so backed up. So I set the appt for Monday morning. Fortunately, the problem is easily duplicated anytime you turn the wheel. But what if it was something that was intermittent? Anyway ill find out Monday.

    Meanwhile, any other ideas? Again, it only happens when turning the wheel left of center, not right.

    Re: Possible Power Steering Issue

    Don't know what it is. Does it make any noise when you do it?

    Re: Possible Power Steering Issue

    I'll listen again with the ac off this time. I believe I may have been hearing something that resembles a low rubber rubbing/grinding noise. Possibly a metal grind but very low. Ill check again.

    Re: Possible Power Steering Issue

    Thanks Gregory.

    Thinking about it. There's definitely something rubbing/grinding that shouldn't be. Some kind of friction. Especially because I feel the vibration not only in the wheel but in my left foot when it's sitting on the dead pedal. Whatever is grinding is causing enough vibration to allow me to feel that.

    And the fact that its only when I turn in one direction that I feel it has to be a big hint as to what it might be. I just don't know enough to diagnose. Ill report on noise tomorrow.
