Hey guys, a 97 manual trans GSX that needs a new rear passenger axle. After calling around alot of places, they are asking me if the car has a locking or non-locking rear diff, and if it had ABS. Even searching through car-part they list both. I was under the assumption that all AWD DSMs had a viscous coupling rear diff ( locking..), is this wrong? If so, how can I tell which this vehicle has? Thanks!
