Servo? Steering linkages?

I've been trying to get my t2009 ready for the Colorado race this weekend. when I was adjusting front toe with the hudy set up station I noticed that if I turn the wheels and then release the steering wheel on the radio, the wheels are not returning to the same position. I don't know if the servo is not accurately returning to center or there is too much play in the steering linkages.

Any thoughts? The steering is shifting 3 - 5 degrees left or right.

Thanks.

Carter, Rich at Hobby Proz and I was talking about this awhile back, and of course I don't recall exactly what was said. Seems like it had to do with if it is a digital servo or not, give him a call..
