when the speed hits 45 the steering wheel starts shaking and the car pulls to one side...do I need a wheel alignment?
shaking on 2001 Ford Expedition
I would recommend a complete inspection of the front suspension, steering, and tires. Any faults should be repaired and then the alignment should be checked and set to factory specs.
