...may have been put in opposing positions (one locked/one free) deliberately, unbeknown to me. Last time I looked several months ago both were free. Would any damage have been done? What should I do next?

Appreciate anybody thoughts with a past similar situation..

 

no your fine. it won't hurt any thing. although it makes the spider gears in your front diff work overtime but as long as there is good oil in the front diff you shouldn't have hurt anything. i have done it while in 4wd even and not hurt anything. i could figure out why i was spinning so much. oops other hub wasn't looked in. pulled right out!

 

...Thx tjbeggs. I'm not used to peekin' at them, always had auto/pushbutton in the cab...
