Steering column movement 84 Bronco fullsize

Have a 1984 ford bronco full size 351 2bbl power steering. W/ 250000+ miles problem is: while holding my steering wheel I can move it upwards and right to left at least an inch to two inches also bcuz of this truck will not start unless I push upwards and to the right on the steering wheel also am having intermittant stalling due to column movement however it can be restarted by putting in nuetral. Also I must turn the keyto extreme on while doing all above. I have taken steering column apart but only as far as taking steering wheel off. My question is how do I tighten up steering column and what could be causing all other problems im experiencing im guessing ignition switch is part of problem but im at a loss as to how im going to fix irregular column movement HELP. Just a sidenote: also truck is lifted and when I get into truck I used steering wheel to help pull me in.
