cAR shakes at 60 mph
My car has 153000 miles.
My car has an automatic transmission.
The tires, tie rods, and rack and pinion are the most common areas to look at for a vibration in the front end. The tires may be out of balance or have a stop leak inside one of them. The tie rods could be worn and loose, and the rack and pinion could have worn out bushings. I would recommend having a professional, such as one from YourMechanic, take a look at your car to diagnose the vibration issue that you are observing.
