Update: I was a little nervous about getting half way done and running into a roadblock so called a mobile truck repair place. Two guys showed up early the next morning and within an hour and a quarter they had it all done. They bottle-jacked it up in front of, and behind, the wheels, just enough for both tires to clear, but didn't remove the wheels. They said the most likely explanation is that the nuts on the U bolts were loose, they checked the other three and two of them needed re-torquing. There was some old rust evident on one of the broken leafs at the break point so I suspect at least one had been broken for a while. It was a bit more expensive than I had anticipated but worth it for peace of mind and not having to spend half a day of vacation on my back in the mud and gravel. For bad luck it wasn't that bad - made it to the campground without catastrophic failure, because it was raining the tires, even though they were rubbing, didn't disintegrate.
I've found that hiring pros to do a job that I could =probably= do, is much better in the long run. :-) 'Sides, I can have a brewski while I watch. :-)
