Lincoln Lincoln Navigator 2007-2017 Drivetrain Specifications

The 2007-2017 Lincoln Navigator features a 4WD or RWD drivetrain configuration, paired with a 5.4L V8 engine producing 310-320 horsepower and 365-390 lb-ft of torque. It includes a 6-speed automatic transmission and an optional electronically controlled 4WD system with low-range gearing. The drivetrain is compatible with towing capacities up to 9,100 lbs, depending on the model year and configuration.

Regular maintenance for the Lincoln Navigator's drivetrain includes checking and replacing the transfer case fluid every 30,000-50,000 miles, inspecting the driveshaft and U-joints for wear, and ensuring the 4WD system is engaged periodically to maintain functionality. Transmission fluid and filter should be replaced every 60,000-100,000 miles, and differential fluid should be changed every 50,000-75,000 miles to ensure optimal performance.

To replace drivetrain components, first, lift the vehicle securely using a jack and stands. For the driveshaft, remove the bolts at the differential and transmission, then slide it out. For the transfer case, disconnect the driveshaft, wiring, and mounting bolts, then lower it carefully. Always refer to the service manual for torque specifications and alignment procedures to ensure proper installation.

Common drivetrain issues include vibrations from worn U-joints or driveshaft imbalance, 4WD system engagement problems due to faulty actuators or sensors, and transmission slipping caused by low fluid levels or worn components. Diagnose vibrations by inspecting the driveshaft and U-joints, and check 4WD system wiring and actuators for engagement issues. Transmission problems may require a fluid check or professional diagnostic tools.

To optimize drivetrain performance, use high-quality synthetic fluids for the transmission, transfer case, and differentials. Regularly inspect and maintain the 4WD system, ensuring it is engaged periodically to prevent seizing. Upgrade to performance driveshafts or U-joints if towing heavy loads. Additionally, ensure proper tire alignment and inflation to reduce strain on the drivetrain components.
