I called the dealer and ask what they recommended. They told me 75/140synthetic, it's $18 a quart. Any input?Thanks

Given the number of rear end failures in early Titans, I would follow their recommendations, though you should be able to find the same lube in the parts store for less. Do you have the finned aluminum rear diff cover on your truck? If not, that's a good upgrade, as it allows for additional oil capacity and cooler running temps.
