I was going through all the snow covered roads today when I got a bit over confident and tried to tackle a 21" wet snow area. I soon got stuck and tried going back and forth in 4wd, then I put it in 4wd low without shifting in neutral but my wheels were completely stopped and then I tried going back and forward. Finally I realized I was high centered and I dug out the bottom and got right out. My question is did I do any damage by going back and forth in 4wd low and by shifting into 4wd low without being in neutral?
