I need to change rear diff oil in a 2008 Prado with an ARB rear locker. In N Qld and thinking 85W-140, GL-5. ARB used to say avoid LSD additives, but it looks like that recommendation has been dropped. SAE J2360 specs look way better than GL-5 so I'd like to find an oil with J2360 certification.
Can you recommend any readily available gear oils, and/or have experience with 75W-90 vs 85W-140? Any clues on how sensitive ARB lockers are to gear oil viscosity? I got the Prado used and don't know what's in it now, but the diff oil still looks good.
