does it make a roaring sound? If so, hubs might be bad. How many miles? Have the hubs been replaced yet?
Check the ball joints. I doubt this could be the culprit, but never know.
Are the lugs and lug nuts in good shape? have they ever been tightened/torqued by air tools? Could be fatigued, stripped, cross-threaded, or inadequately torqued.
Tie rods, of course.
I'll let the others chime in here about sways being broken/snapped/worn.
Otherwise, welcome to the site! Enjoy your stay. You found a good group of folks that have and will dispense invaluable information almost as soon as you post. As often as you can, post pics. We LOVE pics here.
