I had my rack n pinion and its computer recently replaced. After I picked up the car from the dealer I noticed that the steering was easier to turn to the left, but offers a bit of resistance to the right. It's not like the power steering does not work, but there is a noticeable difference. Does anyone else have the same symptom? What could cause it?
