Yes. It was a bad judgement call on my part. The rod was bent only about 2 degrees and I thought I could get by. Live and learn.
They replaced the half-shaft and tie rod. I'm not sure what damage to the CV there was as I didn't get it back to look at but the boot was torn up pretty good and the bearings all fell out. Like I said, it didn't make any disconcerting noises when it was in 4LO, but did when I tried to go into 4HI.

I like the idea of letting the least expensive, easiest to replace, part fail, but carrying some spares sounds like a good idea.
