Don't know what year you're talking about, but I had a problem with the steering wheel assembly in my '88 having too much play. Turned out to be 4 bolts buried deep inside the assembly were loose. Full disassembly was required to get to them. Best you get the details out of a FSM for your year and model. I had to remove the wheel (easy part), then all of the guts underneath, including steering wheel lock, ignition lock, turn signal stalk, and myriad little levers, springs, and rods. Disassemble slowly, take pictures, or make detailed drawings of what goes where, and the orientation of each piece. I believe I've seen something about this in this forum, so I suggest a search here, or here using Google. And please, for safety's sake get it fixed soon.
