Hi all, i am going to change my engine oil this weekend and planning to change gear oil for transfer case and R/F diffs. too. My X is 74K miles it is the time to change oil for TC and RF diffs. I am going to buy gear oil 75w90 at dealer tomorrow. I am not sure how much oil I will use for TC and R/F differentials.
Does anybody know? Thanks so much in advance!
