Stef called me on the the way home from a friend's house to tell me the truck was driving really squirrely and shaking badly in back. Immediately I figured that something in the rear suspension that had been damaged in the collision had given out, and that she'd arrive home with the back end nearly dragging the ground.
I was please to see that the only problem was that she had driven home on a flat tire. The spare on the truck is full sized, so it's not even a financial burden at this time. I'll just buy a retread after the first of the year.
