this happend to me easter last year. we were down at rover park tenterfeild for easter camping. as i was coming back to camp i hit a lil speed bump a bit to fast with a BIG pothole behind it which i couldn't see. on landing there was a loud banging sound, didnt think much of it then but looking at my ute back at camp i realised my car was riding on bump stops on RH side. checked it out and the torsion bar had sheared the internal splines on the rear RH side bracket. has any one heard of this happing? had a 2in EFS and new torsion bars, new rear springs. 2002 d22 fortunatly RACQ towed me for the 4hour round trip.
