    Maybe that is the issue that causing the pull at low speed. Due to small leak the piston is not coming back quickly one side?

    Maybe...possibly...

    More clues. Just had the car up on jack stands and started engine with car in neutral. Right wheel is spinning almost at an idling pace and the left wheel is stationary. WTF?! Isn't neutral supposed to me literally that... neutral?!

    Too late. Car is back down on the ground after I found a new problem to deal with. Leaking brake piston seals. It's scootched over to let the wife park in the garage with me. Gotta love the track day abuse repairs.

    My highly knowledgeable dad and I were discussing this last night and he knew exactly what the problem was. Not really a problem but something that I never even thought of. I'll admit I only have basic knowledge of transmissions compared to engines...

    This is not unusual as the the gears are engaged all the time but rotating on their bearings. When in neutral there is enough drag to cause the output shaft to rotate. The differential will then send that to whichever wheel has the less drag; doesn't take much.

    With that said, I think the issue with the steering is down to the steering angle sensor. The dealer already wanted to charge me $200 to even start looking at the problem so I think i'll wait till i sell the car someday to fix it.

    Don't ya just love the stealers...$200.00 to just look at it?

    Yep very normal to have a little tire rotation on the stands.

    what's going on with the dsc? That's a little disconcerting.

    The DSC cannot function if either the steering angle sensor or wheel speed sensors are not working. I know the wheel speed sensors are good since ABS is still functioning perfectly. The two sensors talk to eachother and the computer knows how fast each wheel should be turning with respect to what angle the steering wheel is turned at. I'm not concerned at all since I don't drive the car in the winter and at the track that last thing I want is another electronic nanny like DSC.
