I had one issue with my brothers Olds rear end.. much
like a dana.. the axle tubes were welded to the case
but at Norwalk the one tube broke the weld free and
that tube would rotate in the housing.. at first I
didnt figure out that the tube was rotating but 1
wheelie bar was way lower than the other.. the welds
were a previous owner and didnt hold... I pulled the
diff and zeroed it up again and re-welded with nickle
rod and its been fine since.... this was in his 8
sec nostalgia altered
