i've changed my gearbox and rear diff.the gearbox feels fine but the rear diff seems to have a problem. when i put the power down through right hand corners and roundabouts in 1st and 2nd gears i get an almighty banging and judder from the rear passenger side. anyone got any ideas what this could be. car is a 93 wrx. thanks
