What are the drivetrain specifications for the 2014-Present Infiniti QX80?

The 2014-Present Infiniti QX80 features a 4WD (four-wheel drive) system with a 7-speed automatic transmission. It is powered by a 5.6L V8 engine producing 400 horsepower and 413 lb-ft of torque. The drivetrain includes a full-time all-wheel-drive system with a two-speed transfer case, offering both high and low-range gearing for off-road capability. It is compatible with various driving modes, including Snow, Tow, and Eco modes.

Q2

What maintenance is required for the Infiniti QX80 drivetrain?

Regular maintenance for the Infiniti QX80 drivetrain includes checking and replacing the transfer case fluid every 30,000 miles, inspecting the driveshaft and CV joints for wear, and ensuring the differential fluid is changed every 60,000 miles. Additionally, the transmission fluid should be replaced every 60,000-100,000 miles, depending on driving conditions. Always refer to the owner’s manual for specific intervals and consult a certified technician.

Q3

How do I replace the drivetrain components on a 2014-Present Infiniti QX80?

Replacing drivetrain components on the Infiniti QX80 requires lifting the vehicle securely and removing the undercarriage shields. For the driveshaft, disconnect it from the differential and transfer case, then install the new one in reverse order. For differential or transfer case replacement, drain the fluid, remove mounting bolts, and carefully detach the unit. Always torque bolts to manufacturer specifications and refill fluids as recommended.

Q4

What should I do if my Infiniti QX80 drivetrain is making noise?

If your drivetrain is making noise, first check for loose or worn components such as the driveshaft, CV joints, or differential mounts. Inspect the fluid levels in the transfer case and differentials. Unusual noises like grinding or whining may indicate worn bearings or gears. If the issue persists, perform a diagnostic scan for error codes and consult a professional technician for further inspection.

Q5

How can I optimize the performance of my Infiniti QX80 drivetrain?

To optimize drivetrain performance, ensure regular maintenance, including fluid changes and component inspections. Use high-quality synthetic fluids for the transmission, transfer case, and differentials. Upgrade to performance tires for better traction and handling. Avoid excessive towing or off-road use without proper preparation. Utilize the vehicle’s driving modes appropriately, such as Tow mode for heavy loads or Eco mode for fuel efficiency.
