(Licenced Technician) -- Loose steering / wander can be caused by almost anything; bad alignment to worn steering linkage to bad balljoints to broken springs, worn steering gear, incorrect tire pressure (too high or too low), worn / mismatched tires, even wear in the steering column can cause this. In extreme cases, I have seen vehicles that would not drive properly, even with a front end that was 100% and an alignment that was all in spec. It turned out the vehicle's frame was still damaged after an accident. I would strongly recommend getting this professionally checked; a 1994 GM likely still has original (read: non-greaseable) front end joints and are likely getting play in them. .
