Searched the forums but havent found a related solution.

I noticed recently that when turning my car, the steering wheel does not return straight all the way. It will slowly straighten halfway and I would then have to manually straighten the wheel myself. I checked the power steering fluid, and it was still half-full. Also, when turning, the steering wheel makes a very light creaking noise (only when turning).

Anyone have any ideas what it could be?

 

You have probably tweaked something in the suspension. Take it to an alignment shop.

 

how old is the car
How many miles on it.

What kind of suspension components do you have on it, all stock or some things have been changed?

 

45k miles about. All stock. I dont think it is an alignment issue because when I am driving straight, the car doesnt really steer towards the left or right on its own.

 

Still could have a problem. Wheels straighten from an adjustment made in the alignment specs. I can't remember which spec it is though. If that spec isn't correct, it could have the effect you're having. There's more to an alignment than simply making the wheels go in a straight line, especially on a car like this with 4 wheel independent suspension.

 

Do you think it could be something else like a loose/worn tie rod or worn rack? I'll probably bring it in for someone to look at this weekend, but not sure if I should bring it in for a general mechanic to look at it first or an alignment place.

 

the rack and pinion has an adjustment for this IIRC. Just take it somewhere ( dealer? ) so that they can adjust it.

 

does the car feels rough and jumpy on the bumps and rough road?
