That sounds like the 4wd is partially engaging. I bet what you smelled was the front diff overheating. If that is the problem, continuing to drive it like that will destroy the diff.

I'd look at the trans and transfer case fluids (levels, color - red, and smell - not burnt) and look under for overflow in the transfer and the trans being low - seal may have gone between them. Could be the diff but thats got gear oil in it. A trip to the trans shop for a free inspection is probably in order. - easy to see on a lift. Lots of Blazer things clunk as they fail.
