Craziest Brake Job I have ever done

Just had a tweeker come by the shop, was selling some wheels and tires that came off a Duramax on craigslist. Asked to test fit one on his rig, got it up in the air and the lug nuts off. Went to grab the wheel to pull it off and there was over an inch of movement in the tie rod, and about an inch at the upper ball joint. Pointed it out and the guy goes, "ohh I wondered why it kept wanting to dive off the road in a corner when I had a trailer on"
