I've got the car booked in to get the exhaust system checked for leaks on Thursday (by the guys who originally fitted it) and thought I'd get them to do the diff swap (open-centre - LSD), and so I need some advice...Given that the LSD is a hybrid (MX83 carrier/MA70 Supra LSD internals) it's going to need a complete fill with oil.
So, how much do I need, and what should I use? I've just had a quote from Toyota on their own "universal stuff (Part no. PZQ9900075, Viscosity rating 85W-90).
Is there better stuff out there? Something more "suited" to this particular diff?
