Be careful out there!

I was helping your neighbor change the spring hanger brackets in his Ford Explorer, we didn't have an extra Jack so I had them hook a tow strap to the side by side he had and had him try to pull the axle back. Well, I got this feeling of vertigo, and movement in my peripheral..... I looked up, seen the frame sliding across the jack stand..and then hopped back! he ended up dragging the damn thing off the jack stand, the entire truck......
