I was driving this morning and the car started to pull to the left, as if my tire had gone flat. I pulled over and found that side of the car to be resting on the tire. I thought the air suspension had gone out in that area, but after having it towed, we found the ball joint to have failed. After looking online, I am thankful it wasn't much worse. If you Google Whompy Wheel Syndrome, you'll see plenty of stories where an accident ensued and lots of damage followed. Now I'm just interested to see what this will cost to fix. Guessing I should have the passenger side replaced, as a precaution, as well.
