Hopefully this isn't one of those, break a birf/axle/hub take out a $500 detroit.
1st, Don't drive on it until you take the birf and axle out. Even though you were able to steer/ get it home, it is possible (if in fact the birf broke) for the birf to become lodged in the knuckle and suddenly limiting your steering.
Next, tear it apart and take pictures and post back!! We love seeing carnage!
Oh, and most likely it was the birf. Stockers are really weak when you're full turn and using the gas petal. It is possible for the locker to break when a birf goes, so be sure to take a look at that too while you're in there.
There is a FSM for an '85 toy on this site (one of the stickys i believe) Print the pages for rebuilding front axle (same for all straight axles) and have at it.
