hi, i have recently installed limited slip differential center in my KE70. the mechanic told me to put normal gear oil, so i did. but when i drove the car, it started to make noises when i take sharp turns. it bothered me a lot so i searched internet what the problem is. i found out that its the gear oil i have put in is wrong or not for LSDs. than searched for oils, unfortunately so many of them that now i am confuse what to do. i asked Toyota frontier, they told me that they have it and it's GL-5 85w-90 1500/L. i am thinking weather it will work or not because on internet people say u'll be needing friction modifier for the noise.
pictures are attached of my LSD center
