Ross, This is exactly what has happened to mine. Nissan put normal oil in my rear diff and it is obviously not operating the way it should. I am so furious with them. However, Nissan are useless and crying over spilt milk is a waste here, unless the diff was damaged, then i would go mental! I plan on purchasing the LSX and running the vehicle for about 100 km, then drain again and fill again, however, with the agents quoting me over R1000 i cannot do this, i need a solution in the form of the cheaper LSX.
I will call around first thing tomorrow for this..... hold thumbs guys!
