I have got a 2005 Mondeo with 22,500 miles on the clock. In the last few weeks I have noticed that the steering wheel wobbles/vibrates when the car is doing between 25- 40 mph. I had the front wheels rebalanced a few days ago and the car has just passed its MOT but the problem is still there. The MOT did pick up that the tracking might be out but would that cause the problem? If not what else could it be?
