I was hoping someone who has swapped their differential oil on their AWD jaguar could help me out. My service manual specifies Castrol 720 BOT 75W90 for the rear differential. However, I can't seem to find the specifications for the front differential. I know the front isn't an E-Diff like the rear, so would it take a different oil? Any help is much appreciated!
