The steering was getting very SHAKEY on the giant green van (MEANGREEN as adjacent drivers often are heard shouting) and since the payload is usually MY kids, I had it checked out.
Turns out it needed all ball joints replaced, and a new tie-rod. Ouch! Spendy, but not nearly as bad as the original quote of $1500. I guess we can afford some gas for this summer...
I did videotape the bearings in action - kinda fun in the rain with an underwater camera. Not fun enough to post, though...
