I was going to take my daughter back to college last weekend and I overheard her talking to her roomate on the phone. "Yeah, if a Semi and a pickup had a baby, that would be my Dad's new truck". With a line like that, I kinda felt I was getting something for all that tuition money I have been spending. Just changed diffs and NV5600 fluids but has anybody come up with a transfer case lube other than the dealer stuff?
