The pin at end of shaft is just a press fit. To remove it, place a socket over one side to receive pin when pressed out with a heavy vice.
Use a five gallon joint compound pail or like to balance steering wheel and shaft while pin is pressed from column in vice. Pin will resist initial movement, once it moves she goes the rest of the way easily. When end of pin is pressed flush with shaft, use a drift punch close in size of pin & hammer to tap it out the rest of the way from shaft.
To replace pin, gently start it into its hole, and press into shaft with vice & socket until centered.
Don’t beat on it with a hammer, it will mushroom and never be removed easily.
