How to Identify Your Axle Ratio
Unlike domestic manufacturers, Nissan does not typically use a door-jamb sticker with RPO codes or a tag on the differential cover to identify the axle ratio. The most reliable way to determine your axle ratio is to use a VIN decoder or consult your vehicle's original window sticker. You can also contact your local Nissan dealer with your VIN, and they can provide you with the vehicle's specifications.
Towing vs MPG Impact
The axle ratio has a significant impact on both towing performance and fuel economy. A numerically higher ratio (like the 3.692 in the Cummins XD) provides more torque to the wheels, which is ideal for towing heavy loads. However, this comes at the cost of fuel economy, as the engine has to run at higher RPMs at cruising speeds. A numerically lower ratio (like the 2.937) is better for fuel economy as it allows the engine to run at lower RPMs on the highway, but it doesn't provide as much pulling power.
Common Issues
At the time of writing, there are no widespread, commonly reported issues with the rear differentials in the 2017 Nissan Titan. However, as with any vehicle, it is possible to experience ring and pinion whine, carrier bearing failure, or other issues over time, especially with heavy use or high mileage. Regular differential fluid changes are the best way to ensure a long service life.
