I'm not sure how far north you were during the 'ice storm' but a lot of it was just a light coating of snow. As long as you have substantial traction, 4 high open is just fine. In all honesty, 4 high can get you 95% 4 high lock will get you...I always caution folks about 4 high lock because their salesperson may say "just throw it on if its snowing or raining...it gives you more traction"...but when you have traction, that can really mess up your transfer case...who knows if there's anything wrong...I asked about the smell because sometimes you get a slight burning smell when the transfer case/4wd system is under a lot of stress. If i had to guess -- it would be that the 4 high lock system was over-run in the recent weather, and now exhibits behavior of older 4wd systems...I'm not exactly sure on the exact mechanics, others here are...I just know that i've seen MANY 4wd systems need to go in reverse to un-engage, but not H2s...
