bravo 35 Report post Posted May 15, 2008 Turn one of the output flanges - does the other one turn the same direction and spin the input flange, or does the opposite one simply turn the opposite direction? The first scenario indicates a LSD, the second an open diff. Quote Share this post Link to post Share on other sites
