It could be several things. When was the last time your brakes were repaired and if so, new brake rotors? If brakes are worn and rotors worn, when coming to a stop they may wobble. There are numerous things on the front end also that can be lose, tie rods, ball joints etc. For free you can go to a reputable front end shop and have it checked out. You have a large number of miles on your vehicle so it has been good to you. It is probably past time that the front end is worn.
