How can i fix my Xbox Force Feedback Steering Wheel?

My Xbox force feedback steering wheel has a problem with it, the problem with it is when i use it if i have the steering wheel straight the car turns to the left so if i want to go straight i have to turn right and its a real pain because you cant use it, the pedals are fine its just the steering wheel ive tried re-connnecting it to the xbox and it didnt work!! also dont say it just the handling of the car becasue ive tried that!
So if you know how to fix it or you have had a problem the same as this before please tell me how you got it fixed!!
Thanks!
