I will be changing the transfer case and rear diff on my 2001 4wd 4Runner. I am not planning on using synthetic but am wondering about the manual specs. One spec calls for GL-5 75w-90 for the transfer case and a second spec calls for GL-5 75w-90 hypoid for the differential. Are these the same or do I need to buy two different products?
