Maytag 25 year old top loading washer

my maytag washer is 30 years old never broke down it washes fine but when spinning it spins to fast and shakes but when stop it slows down is it made to do

I have never heard of this complaint before and I have worked on many units in the last 15 years . The problem may be lack of dampening if the wash basket and tub are not in decent condition . Does the balance ring on top of the tub show any sign of leaking fluid or other problems relating to its attachment to the top end of the tub . If the tub has the four springs at the corners are these in decent condition ? Hope this is of some help .
